1. **Design Strategy**: The user wants a beginner-friendly knitted boxer short (underwear/sleep shorts style). I'll design a simple, comfortable pair of boxer shorts worked in the round on circular needles — no seams, no complex shaping. Worsted weight yarn will give a soft, stretchy fabric. I'll use a simple 2x2 rib waistband and stockinette body, which is perfect for beginners. The construction will be top-down: waistband → body → divide for legs → each leg worked separately in the round. 2. **Construction Plan**: - Worked top-down, in the round - 2x2 rib waistband with elastic/drawstring channel - Stockinette body tube down to crotch point - Divide for two legs (like working a simple yoke split) - Each leg worked in the round with a small rib cuff - Sizes: S, M, L, XL based on hip/waist measurements - Simple short-row or cast-on crotch gusset for comfort (I'll use a simple CO method at the divide — beginner friendly) - Construction: cast on at waist, work down, split at crotch, finish each leg 3. **Quality Assurance**: - Fit: Waistband needs negative ease (elastic/drawstring will gather). Hip circumference needs slight positive ease for comfort. - Crotch divide: Simple approach — work front half, CO a few stitches for crotch, work back half separately or join for legs. I'll use the "divide and CO" method: put front stitches on hold, work back, then pick up and work legs. Actually, simpler for beginners: work body as tube, at crotch divide stitches in half, CO a few bridge stitches at crotch for each leg, work each leg in the round. - Math: Make sure stitch counts are even and divisible by 4 for 2x2 rib. - Yarn amount: Worsted boxer shorts — estimate 300-500 yards depending on size. - Needle size: US 7 / 4.5mm for worsted (slightly smaller for a denser, less see-through fabric) 4. **Final Calculations**: GAUGE: 18 sts × 24 rows = 4 inches (10 cm) in stockinette on US 7 / 4.5mm needles = 4.5 sts per inch Sizes (hip circumference with ~2 inches positive ease): - S: fits 32-34" hip → garment hip = 36" → 36 × 4.5 = 162 sts → round to nearest multiple of 4 = 164 sts - M: fits 36-38" hip → garment hip = 40" → 40 × 4.5 = 180 sts → multiple of 4 = 180 sts ✓ - L: fits 40-42" hip → garment hip = 44" → 44 × 4.5 = 198 sts → round to 200 sts - XL: fits 44-46" hip → garment hip = 48" → 48 × 4.5 = 216 sts ✓ Let me reconsider — worsted on US 7 might be tight. Standard worsted gauge is more like US 8 / 5mm = 18 sts per 4 inches. Let me use US 8 for body and US 7 for ribbing. Actually, let me standardize: - Ribbing: US 7 / 4.5mm - Body: US 8 / 5.0mm - Gauge (body): 18 sts × 24 rnds = 4 inches = 4.5 sts/inch Stitch counts: - S: 36" circumference → 36 × 4.5 = 162 → round to 164 (divisible by 4) ✓ - M: 40" circumference → 40 × 4.5 = 180 (divisible by 4) ✓ - L: 44" circumference → 44 × 4.5 = 198 → round to 200 ✓ - XL: 48" circumference → 48 × 4.5 = 216 (divisible by 4) ✓ Actual finished hip (back-calculated): - S: 164 / 4.5 = 36.4" ✓ - M: 180 / 4.5 = 40" ✓ - L: 200 / 4.5 = 44.4" ✓ - XL: 216 / 4.5 = 48" ✓ Waistband: worked at same stitch count but on smaller needles — waistband will naturally pull in with rib. This is fine for an elastic waistband — the rib stretches to accommodate. Total body length from waist to crotch: ~10 inches for a boxer-short rise - 10" × 6 rnds/inch = 60 rounds (gauge: 24 rnds per 4" = 6 rnds per inch) Wait: 24 rnds / 4 inches = 6 rnds per inch. Yes. Body length (waist to crotch divide): 10 inches = 60 rounds Waistband: 2 inches of 2x2 rib = 12 rounds Leg length: 3 inches = 18 rounds plus rib cuff of 1 inch = 6 rounds → total 24 rounds per leg Crotch gusset: CO 8 sts at center front and center back when dividing for legs. Leg stitches: - S: 164 total → divide: 82 front + 82 back. At crotch divide, put 82 sts on hold for back leg. Front leg: 82 sts + CO 8 gusset = 90 sts for front leg in round. Hmm, this gets complicated. Let me simplify the crotch construction for beginners: **Simpler approach:** At crotch divide point: - Total stitches = all body stitches - Divide total stitches in half: front half and back half - For each leg: use half the total stitches + cast on a small number of bridge stitches For leg circumference: - Leg stitches = half body stitches + bridge sts Half of body sts: - S: 164/2 = 82 sts per half - M: 180/2 = 90 sts per half - L: 200/2 = 100 sts per half - XL: 216/2 = 108 sts per half Bridge cast-on (for inner thigh comfort): 8 sts for all sizes (can be 6-10) Total leg sts: - S: 82 + 8 = 90 sts → leg circumference = 90/4.5 = 20" ✓ (reasonable for upper thigh) - M: 90 + 8 = 98 sts → 98/4.5 = 21.8" ✓ - L: 100 + 8 = 108 sts → 108/4.5 = 24" ✓ - XL: 108 + 8 = 116 sts → 116/4.5 = 25.8" ✓ These are upper thigh circumferences which seem reasonable (typical upper thigh is 18-25"). Actually, boxer shorts don't need to hug the thigh — they're loose. These numbers give a looser fit which is great for boxers. Leg cuff: 1 inch of 2x2 rib. For rib, need divisible by 4: - S: 90 sts — 90/4 = 22.5 → NOT divisible by 4. Adjust to 88 sts: decrease 2 sts when beginning leg, or start leg with 90 and note 90 isn't /4. Let me reconsider. I need leg sts divisible by 4 for 2x2 rib. - S: 82 + 8 = 90 → not divisible by 4. Could use 82 + 6 = 88 ✓ OR 82 + 10 = 92 ✓ - M: 90 + 8 = 98 → not divisible by 4. Use 90 + 6 = 96 ✓ OR 90 + 10 = 100 ✓ - L: 100 + 8 = 108 ✓ (108/4 = 27) ✓ - XL: 108 + 8 = 116 → 116/4 = 29 → not divisible by 4. Use 108 + 12 = 120 ✓ or 108 + 4 = 112 ✓ This is getting messy. Let me just say "decrease to nearest multiple of 4 for rib cuff" OR skip the 2x2 rib cuff and use a simple hem fold, or just use a 1x1 rib (divisible by 2). Actually, let me use 1x1 rib for leg cuffs — divisible by 2, so any even number works. All leg sts are even: - S: 90 ✓ (even) - M: 98 ✓ (even) - L: 108 ✓ (even) - XL: 116 ✓ (even) For waistband 2x2 rib, body sts are all divisible by 4: - S: 164 ✓ (164/4 = 41) - M: 180 ✓ (180/4 = 45) - L: 200 ✓ (200/4 = 50) - XL: 216 ✓ (216/4 = 54) Now let me also think about the waistband. For a drawstring/elastic channel: - Work 2x2 rib for 1.5 inches - Fold line: purl one round - Work another 1.5 inches of stockinette or reverse stockinette for the inside of the waistband fold - Fold and tack down to create a channel - Thread elastic through OR simpler for beginners: just work 2x2 rib for 2 inches with a folded hem for elastic casing. Even simpler: work 2x2 rib for 2 inches and use a length of elastic sewn directly to the inside (easier for beginners than a casing). I'll go with: 1 inch rib + purl round + 1 inch stockinette for elastic casing. Total 2 inch waistband. Rnds for waistband: - Rib portion: 1 inch × 6 rnds/inch = 6 rnds of 2x2 rib - Purl fold rnd: 1 rnd - Casing portion: 1 inch × 6 rnds/inch = 6 rnds stockinette - Total: 13 rnds Actually that seems thin. Let me do 1.5" rib + fold + 1.5" casing: - 9 rnds rib + 1 purl rnd + 9 rnds St st = 19 rnds total - Total waistband depth visible: 1.5" + 0.17" + 1.5" = ~3" folded = 1.5" on outside ✓ Hmm. Let me simplify. For a beginner, let's just do: - Work 2x2 rib for 2 inches (12 rounds) on smaller needles - This is the visible waistband - Separately: sew elastic to inside of rib OR fold and sew a simple elastic casing Let's go with: work 2 inches (12 rnds) of 2x2 rib for waistband. Cast on with backward loop (easy) then work rib. Thread elastic through using tapestry needle, or sew to WS. Simple. Actually the clearest beginner approach: - CO, work 1.5" (9 rnds) rib on smaller needle - Change to larger needle for body - At end, fold waistband to WS and sew down to form casing, thread elastic OR: Work body first, pick up for waistband. No, top-down is cleaner. Let me just write the pattern clearly: **CONSTRUCTION SUMMARY:** 1. CO at waist on smaller circular needles 2. Work 2x2 rib waistband for 1.5 inches (9 rnds) 3. Change to larger needles, work stockinette body for 10 inches (60 rnds) 4. Divide for legs: place half sts on holder, CO bridge sts, work first leg in round 5. Work second leg 6. Fold waistband and sew elastic casing 7. Weave in ends Now let me verify yarn amounts: Worsted weight = ~200 yards per 100g skein typically Stockinette body: circumference × body length in rnds For M (180 sts × 60 rnds) + legs (98 sts × 30 rnds × 2 legs) + waistband (180 sts × 9 rnds) Rough yardage estimate: - Each stitch ≈ about 0.5" of yarn (very rough for worsted) - Actually let me use a more reliable method: yards per square inch At 18 sts × 24 rows per 4" = per square inch: 4.5 sts × 6 rows = 27 stitches per sq inch Worsted yarn uses about 0.5 yards per sq inch of stockinette (very rough estimate) Garment area: - Body: 36" circumference × 10" long = 360 sq in (for M, 40" circ = 400 sq in) - Two legs: 2 × (22" circ × 4" long) = 176 sq in (for M, ~21.8" × 4" × 2 = 174 sq in) - Total: ~574 sq in At ~0.5 yards/sq inch (very rough): 287 yards... that seems too high but boxers are fairly large garments. Actually let me look at it differently. A typical worsted adult sweater sleeve uses about 150-200 yards. Boxer shorts are like two partial sleeves + a tube. Estimate: - S: ~300 yards - M: ~350 yards - L: ~400 yards - XL: ~450 yards That seems reasonable. I'll recommend 2 skeins of worsted (typically 200 yards each = 400 yards) to be safe for all sizes, with specific amounts listed. Let me now write the pattern body length calculation more carefully. Total length from top of waistband to bottom of leg = 14 inches: - Waistband: 1.5" - Body (waist to crotch): 10" (the "rise") - Leg: 3" - Leg rib: 0.5" Total: 15" — that's a reasonable boxer short length. Body rounds (waist to crotch): - Worked on larger needles after waistband - 10 inches × 6 rnds/inch = 60 rounds ✓ Leg rounds: - 3 inches stockinette × 6 rnds/inch = 18 rounds - 0.5 inch 1x1 rib = 3 rounds (very short — let me make it 1 inch = 6 rounds of rib) - Total leg: 18 rounds stockinette + 6 rounds rib = 24 rounds Bind off: stretchy bind off for leg cuffs. **NEEDLE SIZES:** - US 7 / 4.5mm: 32" or 40" circular for waistband - US 8 / 5.0mm: 32" or 40" circular for body - US 7 / 4.5mm: 16" circular or DPNs for legs - (Or use magic loop technique throughout) **NOTIONS:** - Stitch markers (2-4) - Stitch holders or scrap yarn - Tapestry needle - 1-2 inches wide elastic, cut to waist measurement - Sewing needle and thread for elastic Let me now do the complete size chart: | Size | Hip Circumference | Finished Hip | CO Sts | Body Rnds | Leg Bridge CO | Total Leg Sts | |------|----------|---------|-------|-----------|--------------|------------| | S | 32-34" | 36.4" | 164 | 60 | 8 | 90 | | M | 36-38" | 40" | 180 | 60 | 8 | 98 | | L | 40-42" | 44.4" | 200 | 60 | 8 | 108 | | XL | 44-46" | 48" | 216 | 60 | 8 | 124... | Wait XL: 216/2 = 108 + 8 = 116. Let me recheck: - XL body CO: 216 sts - At crotch divide: 216/2 = 108 sts per leg half - Bridge CO: 8 sts - Total per leg: 108 + 8 = 116 sts - Leg circumference: 116/4.5 = 25.8" ✓ All looks good. Now let me write the actual pattern. One more thing: marker placement. I'll place BOR marker and a second marker at halfway point (front/back divide). When working body, just knit every round. At divide, that second marker shows where to split. Let me also think about the crotch more carefully. When dividing: - Sts 1-82 (S) are "front" sts, sts 83-164 are "back" sts - Work front sts, CO 8 sts for crotch bridge, join to form round for FIRST LEG → 90 sts total - The 82 back sts sit on holder - Work first leg 24 rnds, BO - Return to held 82 back sts, rejoin yarn, CO 8 sts for second crotch bridge, join into round → 90 sts - Work second leg, BO Wait — both legs need to pick up from the crotch. Let me think about this more carefully. At the divide point, we have the full tube. The marker is at center back (or center front). Actually, the standard approach for pants knitting: - At divide, the "front crotch" and "back crotch" are at the bottom of the tube - Divide: front half sts and back half sts - For leg 1: start with front half, CO bridge sts, put back half on hold - Wait, this doesn't work neatly because both legs share the tube Let me think of it as: at the crotch point, the tube splits into two leg tubes. The bridge sts fill in the crotch curve. Standard method: - All body sts are in a circle - Mark center front and center back - First leg: work from center front marker to center back marker (half of sts = front leg sts), CO bridge sts, turn and work in round → leg 1 - Second leg: the remaining sts are the second leg sts Actually, let me use the simple "divide in half" approach clearly: **AT CROTCH DIVIDE:** - Knit to the halfway marker (this is the center of the crotch/front) - Place next 82 sts on holder (these are the back leg sts for leg 2... Hmm, I'm overcomplicating this. Here's the clean beginner version: The body tube is a single tube. At crotch level, we need to create two leg tubes. Think of it as the bottom of the tube being where you split. **CLEANER APPROACH:** - Work body as tube down to crotch point (60 rnds for M) - Round 61 (first divide round): - Knit first 90 sts (half of 180), place remaining 90 sts on holder - CO 8 sts using backward loop cast-on → 90 + 8 = 98 sts on needle - Place marker, join to work in round - Work leg 1: 18 rnds St st, 6 rnds 1x1 rib, BO - Return to held 90 sts - Rejoin yarn at one end of held sts - CO 8 sts → 90 + 8 = 98 sts - Place marker, join to work in round - Work leg 2: same as leg 1 This is clean and beginner-friendly! The 8 CO sts form the inner crotch seam area. Now let me also reconsider the waistband elastic casing. For a truly beginner-friendly approach, I'll do: - CO, work 2x2 rib for 2" (the entire visible waistband) - After body is complete, fold the first inch of rib to inside and slip-stitch to form elastic casing - Thread elastic through, sew ends together - This means the visible waistband is 1" of rib (the outer fold), and the inner inch becomes the casing OR, even simpler: just work rib, use a wide elastic, and tack elastic directly to inside of waistband. No casing needed. I'll do the casing option since it's neater. Work 2.5" of rib total: - 2.5" × 6 rnds/inch = 15 rnds - Fold 1" to inside to form casing = fold at round 6 - Outer visible rib = 1.5" - Inner casing = 1" for 3/4" elastic Actually let me keep it simple and just say: - Work waistband: cast on, 2x2 rib for 2" (12 rnds) on smaller needles - The elastic is sewn directly to the inside of the waistband with thread This is MUCH simpler for beginners and the instructions stay clear. The rib will naturally stretch with the elastic. OK let me now finalize all numbers and write the pattern: **GAUGE:** 18 sts × 24 rnds = 4 inches (10 cm) in stockinette on US 8 / 5.0mm needles = 4.5 sts per inch, 6 rnds per inch **SIZES:** S (M, L, XL) Fits hips: 32-34 (36-38, 40-42, 44-46) inches Finished hip circumference: 36.5 (40, 44.5, 48) inches (includes ~2-3" positive ease) **CO STITCHES:** 164 (180, 200, 216) **WAISTBAND:** 12 rnds of 2x2 rib on US 7 needles (2 inches) **BODY:** 60 rnds stockinette on US 8 needles (10 inches) **CROTCH BRIDGE CO:** 8 sts for all sizes (worked at divide) **LEG STITCHES:** Half of CO + bridge: - S: 164/2 + 8 = 82 + 8 = 90 sts - M: 180/2 + 8 = 90 + 8 = 98 sts - L: 200/2 + 8 = 100 + 8 = 108 sts - XL: 216/2 + 8 = 108 + 8 = 116 sts **LEG:** 18 rnds stockinette (3 inches) + 6 rnds 1x1 rib (1 inch) = 24 rnds total (4 inches) 1x1 rib divisibility check: - 90/2 = 45 ✓ (odd but 1x1 rib just needs even number: 90 is even ✓) - 98/2 = 49 ✓ (98 is even ✓) - 108/2 = 54 ✓ (108 is even ✓) - 116/2 = 58 ✓ (116 is even ✓) All even numbers → 1x1 rib works ✓ **TOTAL LENGTH:** - Waistband: 2" - Body: 10" - Leg (St st + rib): 4" - Total: 16" from top of waistband to bottom of leg cuff ✓ (standard boxer shorts) **YARDAGE ESTIMATE:** Using formula: sts × rnds × yards per stitch For worsted, approximately 1 yard per 10 stitches (rough estimate per round... let me use a better method) Better estimate: - Circumference in inches × number of rounds × yards per inch of yarn - For worsted: approximately 0.08-0.1 yards per stitch per round... Let me use the simple "row yardage" approach: Each round ≈ (circumference in sts ÷ 18 sts per 4 in) × 4 in ÷ 36 in/yard × some factor... Actually, simplest: for worsted weight, 1 stitch uses approximately 0.5 to 0.6 inches of yarn. Total stitches worked (sts × rnds): - S: Waistband (164×12) + Body (164×60) + 2 legs (90×24×2) = 1968 + 9840 + 4320 = 16,128 sts × 0.55" = 8,870" ÷ 36 = ~246 yards. Add 20% for safety = 295 yards ≈ 300 yards - M: (180×12) + (180×60) + (98×24×2) = 2160 + 10800 + 4704 = 17,664 × 0.55 = 9715" ÷ 36 = 270 + 20% = 324 ≈ 325 yards - L: (200×12) + (200×60) + (108×24×2) = 2400 + 12000 + 5184 = 19,584 × 0.55 = 10771" ÷ 36 = 299 + 20% = 359 ≈ 360 yards - XL: (216×12) + (216×60) + (116×24×2) = 2592 + 12960 + 5568 = 21,120 × 0.55 = 11616" ÷ 36 = 323 + 20% = 387 ≈ 390 yards So recommend: - S: 300 yards (2 skeins of 200 yds = 400 yds — 1 skein may not be enough) - M: 325 yards - L: 360 yards - XL: 390 yards Recommend 2 skeins of worsted weight yarn (approximately 200 yards each), or 1 skein of 400+ yards. Note: Some worsted skeins come in 218 yard (200m) or 220 yard amounts. Two skeins should cover all sizes. Let me round up and say 350 (375, 400, 425) yards to be safe. Now let me think about the CO method. For a waistband, long-tail cast-on is nice and stretchy. I'll recommend that. Also, for binding off, I'll recommend a stretchy bind-off (like k2tog, slip back, or the simple stretchy BO) for leg cuffs. One more consideration: the waistband cast on. Since we're working top-down in the round: - Use long-tail CO, join to work in round, being careful not to twist - Place BOR marker The body is a simple tube — just knit every round. Easy for beginners! Now, should I include a photo schematic? No, text pattern only. Let me also think about yarn type for boxer shorts. Cotton or cotton-blend would be ideal for underwear. However, the spec says worsted weight and doesn't specify fiber. I should note that a cotton or cotton-blend worsted is recommended for comfort and washability. Okay, I think I have everything I need. Let me write the complete pattern now. Wait — one more check on the "split for legs" section. I want to make sure I'm describing this correctly: At the crotch divide: - Working in round, all 164 sts are on needle (for S) - Stop at the BOR marker (which is at center back — I'll re-establish this) Hmm, where is BOR at this point? BOR should be at center back (or side). Let me place BOR at side seam position and a second marker at the other side. Actually for this construction, place BOR at center back. For the divide: - At end of round 60 of body, you've just finished the round and are at BOR (center back) - Leg 1 (right leg / front): Knit 82 sts (for S), turn work so you're now working these 82 sts as a flat section? No — we want to work in the round. Let me re-approach: - BOR is at center back - Sts 1-82: right back + right front (these will form the right leg) - Sts 83-164: left front + left back (these will form the left leg) For right leg: work sts 1-82, cast on 8 sts, join to work in round with these 90 sts. The remaining sts 83-164 go on holder. For left leg: after finishing right leg, return to held sts 83-164, CO 8 sts, join in round. Yes this is correct! But wait — when knitting the body, where is the front and back? For boxer shorts, there's essentially no front/back difference (it's a symmetrical tube), so it doesn't matter which side we call "front" or "back." The BOR can just be at one side. Also: I should add a note about the crotch CO sts potentially leaving a small gap. Beginner note: these sts can be tightened up with the tapestry needle when finishing. Also, I realize I should address the waistband orientation. We CO at the waist, so: - Row 1 of rib is worked with the inside facing out initially? - Actually, when working in the round from the cast-on edge, the right side is facing you throughout. - For the waistband, the outside of the shorts will be the RS. One final thought: since this is a BEGINNER pattern for boxer shorts, I should note that these are meant as sleepwear/loungewear/fashion boxers (not form-fitting underwear). Knitted fabric with worsted weight is fine for this purpose. Alright, I have everything planned. Let me write the verification and pattern now.

[PRE-FLIGHT CHECKS] 1. **Completeness**: ✅ Pattern includes title, description, materials, gauge, sizes, abbreviations, pattern notes, step-by-step instructions, and finishing. 2. **Consistency — Stitch Count Verification:** - CO Sts: 164 (180, 200, 216) — all divisible by 4<planning> 1. **Design Strategy**: The user wants knitted boxer shorts at a beginner difficulty level. I'll design a simple, practical pair of boxer shorts using worsted weight yarn. Construction will be kept simple for beginners: worked flat in two identical panels (front and back) seamed at the sides and inseam, with a simple ribbed waistband and leg bands. I'll avoid complex shaping and use minimal techniques: cast on, bind off, knit, purl, basic decreases, and picking up stitches. I'll provide sizing for Small, Medium, Large, and XL based on standard hip measurements. 2. **Construction Plan**: - Work two identical rectangular panels (front and back) with gentle hip/crotch shaping - Each panel is worked flat from the waistband down - Simple crotch shaping using bind-offs and decreases - Seam side seams and inseams - Pick up stitches around leg openings for ribbed leg bands - Ribbed waistband worked flat and seamed, or picked up after body is assembled - Elastic threaded through waistband channel for practical wearability - Main stitch: 2x2 Rib for waistband/leg bands; Stockinette for body 3. **Quality Assurance**: - Boxer shorts need ease — I'll add 2–3 inches of positive ease for comfort - Worsted weight yarn may feel warm; I should note yarn fiber choices (cotton or cotton blend recommended) - Crotch depth and rise are critical measurements — I'll use standard measurements and provide guidance - Inseam length is short for boxers (typically 2–4 inches) - Need to verify that crotch bind-off + decrease shaping produces a functional crotch curve - Waistband needs to accommodate elastic for a beginner-friendly, functional finish - Must verify all stitch counts at each stage are consistent 4. **Final Calculations**: Standard gauge for worsted on US 7: approximately 20 sts / 28 rows = 4 inches (10 cm) So: 5 sts per inch, 7 rows per inch Sizes (finished hip circumference with ease): - S: 32–34" hips → finished 36" → each panel 18" wide → 90 sts - M: 36–38" hips → finished 40" → each panel 20" wide → 100 sts - L: 40–42" hips → finished 44" → each panel 22" wide → 110 sts - XL: 44–46" hips → finished 48" → each panel 24" wide → 120 sts Total length (waistband to crotch = rise): Standard front rise: approx 11–12 inches Waistband: 1.5 inches (worked in 2x2 rib) = ~10 rows Body length to crotch shaping: 9 inches = ~63 rows Crotch shaping: 2 inches = ~14 rows Total rows (excluding waistband): ~77 rows Crotch bind-off (center): 2 inches = 10 sts Then decrease 1 st each side every RS row for 1 inch = 7 rows = 7 sts each side Remaining sts at top of leg opening (each leg): - S: (90 - 10) / 2 = 40 sts, then -7 each side, wait — let me re-think the construction. Actually, let me reconsider the construction for clarity for beginners: REVISED CONSTRUCTION: Each panel is worked bottom-up (from crotch area up to waist). Actually, top-down is more intuitive for beginners — cast on at waist, work down. TOP-DOWN APPROACH: Cast on at waist with 2x2 rib for waistband, then work body in stockinette down to crotch shaping, then shape crotch (bind off center sts for gusset, work each leg opening edge). Actually, let me think about this more carefully. For a simple beginner pattern, I'll work each panel flat from waist down: 1. Cast on full hip width 2. Work 1.5" of 2x2 rib for waistband 3. Work stockinette for body until crotch point 4. Shape crotch: bind off center stitches, then work each side separately with slight shaping, or simply shape the crotch curve For the crotch, a simple approach: - Work to crotch point, then bind off center sts - Work each leg side separately for the inseam length - This creates the two leg openings Let me establish clean numbers: GAUGE: 20 sts / 28 rows = 4" (using US 7 / 4.5mm needles) = 5 sts per inch, 7 rows per inch SIZE CHART (finished measurements with 2-3" ease): S (fits 32-34" hips): finished hip = 36", each panel = 18" wide = 90 sts M (fits 36-38" hips): finished hip = 40", each panel = 20" wide = 100 sts L (fits 40-42" hips): finished hip = 44", each panel = 22" wide = 110 sts XL (fits 44-46" hips): finished hip = 48", each panel = 24" wide = 120 sts Note: 90 and 100 and 110 and 120 are all divisible by 4 for 2x2 rib ✓ RISE (waist to crotch, including waistband): Standard: 11" total Waistband: 1.5" = 11 rows (round to 10 rows for cleanliness, approximately 1.5") Body: 9.5" = 67 rows Total rise rows: 77 rows CROTCH SHAPING: Crotch bind-off at center: 2" = 10 sts (all sizes — this is a fixed measurement) After center bind-off, work each leg side for inseam: Inseam: 3" = 21 rows During inseam rows: decrease 1 st at inner edge (inseam side) every 4th row 21 rows / 4 = 5 decreases each side Let me verify remaining sts after all shaping (this will form the leg opening): After center bind-off: - S: (90 - 10) / 2 = 40 sts each side → -5 dec = 35 sts each side at inseam BO - M: (100 - 10) / 2 = 45 sts each side → -5 dec = 40 sts each side - L: (110 - 10) / 2 = 50 sts each side → -5 dec = 45 sts each side - XL: (120 - 10) / 2 = 55 sts each side → -5 dec = 50 sts each side At end of inseam, bind off all remaining sts for each leg hem. FINISHING: Seam front and back panels at side seams and inseams. Pick up sts around leg openings for 2x2 rib leg bands, work 1" then bind off. Waistband: work first, then fold over and sew to create channel for elastic. Actually, let me reconsider waistband. For beginner-friendliness, I'll work waistband as part of the cast-on (2x2 rib) and thread elastic directly through it. Better approach: after assembling, pick up sts around waist, work 3" of 2x2 rib, fold in half, sew down leaving gap for elastic. That's cleaner. REVISED PLAN: - Cast on for hip width in 2x2 rib, work 0" before stockinette... No, simplest approach for beginners: - Cast on at waist - Work 1.5" 2x2 rib (waistband) - Work stockinette to crotch - Shape crotch with center bind-off - Work each leg tab separately for inseam depth with decreases - Bind off - Seam panels - Pick up for leg bands - Thread elastic through waistband fold Wait — if I cast on at the waist, the waistband is at the top. I need to make it a fold-over for elastic. So I'll work 3" of 2x2 rib at the start, which will fold in half to create a 1.5" waistband casing. Let me finalize waistband: Work 3" of 2x2 rib = 21 rows, then switch to stockinette. After assembly, fold waistband in half to inside and sew down, leaving a gap for elastic. FINAL STITCH COUNTS VERIFICATION: Each panel: Cast on: S=90, M=100, L=110, XL=120 (all ÷4 for 2x2 rib ✓) Waistband: Work 21 rows of 2x2 rib Body: Work in stockinette for 9.5" = 67 rows Crotch shaping row: BO center 10 sts Remaining each side: S=40, M=45, L=50, XL=55 Work each leg side separately: Row 1 (WS): purl across Then: Dec 1 st at inner edge (ssk at beg of RS rows or k2tog at end) every 4th row, 5 times Work for 3" total = 21 rows After 5 decreases: S: 40-5 = 35 sts M: 45-5 = 40 sts L: 50-5 = 45 sts XL: 55-5 = 50 sts Bind off all sts. LEG BAND (picked up after assembly): Leg opening perimeter = inseam (3") + crotch bind-off (1" each side = half of 2") + outer leg edge (3") + top... Actually leg opening = 2 × inseam edges (3" each side from front and back) + bound off sts (from crotch on front and back) Let me calculate leg opening pickup: - Front inseam edge: 21 rows = 21 sts (pick up 3 sts per 4 rows = ~16... ) Hmm, for a pickup rate: standard is 3 sts for every 4 rows. Inseam seam has rows from both front and back: each panel has 21 rows along inseam edge. After seaming, the inseam is 21 rows on each side. Actually for leg band, I'll just give an approximate pickup count and note that knitters should pick up evenly and adjust to nearest multiple of 4. Leg opening circumference: The leg opening is formed by: - 2 × (inseam edge of 3" = 21 rows per panel, but after seaming it's one edge) ... Let me simplify this. After seaming front and back: The leg opening has: - 2 inseam edges (front + back inseam, each 3" of row edges) - But these are seamed together at the inseam seam... Wait. Let me reconsider the geometry: The boxer short has: - 2 side seams (joining front and back panels at sides) - 1 crotch seam (joining front crotch bind-off to back crotch bind-off at bottom) - 2 inseam seams (joining front and back leg sides) Each leg opening is formed by: - The bound-off sts at the bottom of each leg side (front: 35/40/45/50 sts + back: 35/40/45/50 sts) - The row edges along the inner legs (not seamed — these form the leg circumference at the bottom) Hmm wait. I need to reconsider. When you seam the inseams together, the leg opening at the bottom is actually formed by the bound-off sts of front leg AND back leg (these are what you'd pick up from), plus... Actually in typical flat boxer construction: - Front and back are each shaped - Side seams join them at sides - Crotch seam joins the center bind-offs - Inseam seams join the inner leg row edges of front to back inner leg row edges The leg BAND circumference = bound-off sts of front leg + bound-off sts of back leg (since the row edges become the inseams and are seamed shut) So leg opening = front leg BO sts + back leg BO sts: S: 35 + 35 = 70 sts M: 40 + 40 = 80 sts L: 45 + 45 = 90 sts XL: 50 + 50 = 100 sts All divisible by 4 for 2x2 rib! ✓ Leg band: Work 1" = 7 rows of 2x2 rib, then bind off in rib. YARDAGE ESTIMATE: Worsted weight: approximately 200 yards per 100g skein Estimated yardage: - Each panel approx: width × length in sts × rows / sts per yard - Roughly: for worsted stockinette, about 100-120 yds per square foot of fabric - Panel dimensions: 18-24" wide × 12.5" long (waistband + body) = 1.5-2 sq ft per panel - 2 panels = 3-4 sq ft → approx 300-480 yards - Let me estimate conservatively: 400-600 yards total across sizes More precise estimation: Total sts per row (both panels): 2 × 90-120 = 180-240 sts Total rows: 21 (waistband) + 67 (body) + 21 (inseam) = 109 rows Plus additional for smaller sections At worsted weight: roughly 1 yard per 3-4 sts per row Total st-rows: ~190 avg sts × 109 rows = 20,710 st-rows ÷ 3.5 = ~5,917 yards... that can't be right. Let me use a different method. For worsted weight: - A standard adult sweater front uses about 300-400 yards - Boxer shorts have much less fabric — about 1/3 to 1/4 of a sweater - Estimate: 300-500 yards depending on size I'll state: 300 (S), 350 (M), 400 (L), 450 (XL) yards, recommend 2 skeins of 200-220 yd worsted. NEEDLE SIZES: Body: US 7 / 4.5mm (standard for worsted, gives slight drape) Rib: US 6 / 4.0mm (one size down for tighter rib) NOTIONS: - Elastic: 1" wide, length = waist measurement - Tapestry needle - Stitch markers - Scissors All math checks out.
