1. **Design Strategy**: - Top-down raglan pullover in stockinette stitch - Size Small only requested (34-36" bust), with ~2-4" positive ease = ~38" finished bust - Sport weight yarn, UK English terminology, metric first - Crew neck (default per template) - Easy difficulty level — keep instructions clear, minimal complex techniques - Tension/gauge for sport weight: typically 24 sts × 32 rows = 10 cm (4") in stockinette on 3.5mm or 3.75mm needles - I'll use 24 sts / 32 rows per 10 cm on 3.75mm needles (a common sport weight tension) 2. **Construction Plan**: - Cast on neckline stitches for crew neck - Set up raglan markers (4 raglan lines dividing: back, 2 sleeves, front) - Work raglan increases every other round (M1L before marker, M1R after marker) = 8 increases per increase round - Work yoke to armhole depth - Separate sleeves onto holders - Cast on underarm stitches, join body, work to hem - Add ribbing at hem - Pick up sleeves, work down to cuff with decreases - Add ribbed cuffs 3. **Quality Assurance**: - Verify stitch counts at every stage - Ensure raglan math is consistent - Check armhole depth is appropriate for size small - Ensure sleeve decreases are evenly spaced - Keep instructions simple for "easy" difficulty - UK terminology throughout 4. **Final Calculations**: **Tension**: 24 sts × 32 rows = 10 cm in stockinette on 3.75mm needles **Size Small target**: Finished bust = 96 cm (38") with ~2-4" positive ease over 34-36" bust. **Key measurements for Size Small**: - Finished bust circumference: 96 cm (38") - Finished length (underarm to hem): 38 cm (15") - Armhole depth (yoke depth at side): approximately 20 cm (8") - Upper sleeve circumference: ~35 cm (14") - Sleeve length (underarm to cuff): 45 cm (17.75") - Cuff circumference: ~20 cm (8") **Stitch counts**: Body stitches at underarm = 96 cm × 24 sts / 10 cm = 230.4 → 232 sts (divisible by 4 for ease, actually let me check: 232 / 2 = 116 front + 116 back — works) Wait, let me be more precise. Total body circumference = 96 cm. Body sts = 24 × 96 / 10 = 230.4 → round to 232 sts (front + back = 116 each) **Sleeve sts at upper arm**: Upper sleeve circumference = 35 cm Sleeve sts = 24 × 35 / 10 = 84 sts per sleeve **Raglan yoke construction**: At cast-on (crew neck): The yoke is divided into: - Back sts - 2 raglan "seam" sts (1 each raglan line, or markers only) - Front sts - 2 sleeve sections Standard crew neck cast-on for sport weight size small: Neckline circumference ≈ 40 cm (16") Neckline sts = 24 × 40 / 10 = 96 sts Let me distribute these across sections. A typical raglan setup uses: - 4 raglan seam stitches (1 st per raglan line, so 4 marker sts) - Remaining sts split between back, front, and sleeves Total neck sts = 96 sts Distribution at cast-on: - Back: 32 sts - Front: 28 sts (fewer to allow for neckline — crew neck typically slightly shallower at front... actually for simplicity at easy level, let's keep front and back equal) - Actually for easy level crew neck: keep front = back, and sleeves smaller - Let's use: Back = 30, Front = 30, each Sleeve = 14, Raglan markers = 4 seam sts... Let me use a common approach with just markers (no dedicated seam stitches) for easy construction: Total CO = 96 sts Back = 32 sts Front = 32 sts Each sleeve = 14 sts Raglan sections: 4 markers 32 + 32 + 14 + 14 = 92 sts + 4 markers... Actually with no dedicated seam sts: Back + Front + Sleeve + Sleeve = 32 + 32 + 14 + 14 = 92. Hmm, let me target 92 cast on. OR let me just use 1 seam stitch at each raglan line (4 seam sts total): Back = 30, Front = 30, Sleeves = 13 each, Seam sts = 4 × 1 = 4 Total = 30 + 30 + 13 + 13 + 4 = 90 sts Neckline = 90 sts → neckline circumference = 90/24 × 10 = 37.5 cm (14.75") — that's reasonable for a crew neck. Let me try without seam stitches for simplicity (easier pattern): CO 88 sts Back = 30, Front = 28, Sleeves = 15 each 30 + 28 + 15 + 15 = 88 ✓ Neckline = 88/24 × 10 = 36.7 cm (14.4") — good for crew neck After ribbed neckband, then start raglan increases. Actually, let me reconsider. Let me pick cleaner numbers. **Let me restart the math carefully:** Tension: 24 sts / 32 rows per 10 cm Target finished bust: 96 cm (38") Body sts needed = 96 × 24 / 10 = 230.4 → 232 sts total in round for body Front = 116, Back = 116 Target upper sleeve: 35 cm circumference Sleeve sts = 35 × 24 / 10 = 84 sts per sleeve **Underarm cast-on**: Typically 6-10 sts cast on at underarm for each side Let's use 8 sts each underarm. So at separation: Body sts from yoke = 232 - (2 × 8) = 232 - 16 = 216 sts from yoke for body But body sts from yoke (front + back) at separation = 216 sts... meaning front = 108, back = 108 Each sleeve sts at separation: 84 - 8 = 76 sts from yoke per sleeve **Total yoke sts at separation**: Front (108) + Back (108) + Sleeve (76) + Sleeve (76) = 368 sts Plus 4 markers (no seam sts in this simple version) = 368 sts **Cast-on sts for neckline**: CO = 88 sts (let me verify this works) Back CO = 30, Front CO = 28, each Sleeve CO = 15 Total CO = 30 + 28 + 15 + 15 = 88 sts After the neckband, we start raglan increases. **Raglan increase rounds**: Each increase round adds 8 sts (2 per raglan line × 4 lines) We need to go from: - Front: 28 → 108 sts = +80 sts = 40 increase rounds for front - Back: 30 → 108 sts = +78 sts = 39 increase rounds for back Hmm, front and back need different numbers of increases, which doesn't work in standard raglan (both increase at same rate). Let me adjust CO to make front = back. Set Front CO = Back CO = 29, each Sleeve = 15 Total = 29 + 29 + 15 + 15 = 88 sts ✓ Now: Front 29 → 108 = +79 (not even — needs to be even for symmetrical increases) Let me adjust final body counts. Actually, I need body at separation to have even numbers when divided by front and back. Let me work backwards more carefully: CO sts for body and sleeve sections must satisfy: - CO_back + (2 × num_increase_rounds) = back_sts_at_separation - CO_front + (2 × num_increase_rounds) = front_sts_at_separation - CO_sleeve + (2 × num_increase_rounds) = sleeve_sts_at_separation Since front and back increase at same rate, if CO_front = CO_back, then front_sep = back_sep. For sleeves and body: same number of increase rounds, so all sections determined by CO and number of rounds. Let n = number of raglan increase rounds front_sep = CO_front + 2n back_sep = CO_back + 2n sleeve_sep = CO_sleeve + 2n (each sleeve) Total body sts at sep (before adding underarm) = front_sep + back_sep Total body sts in round = front_sep + back_sep + 2 × underarm_sts = 232 So front_sep + back_sep = 232 - 16 = 216 If front = back: each = 108 sleeve_sep = 84 - 8 = 76 (subtracting underarm sts) Now: n = (108 - CO_front) / 2 For this to be whole number: CO_front must be even. Also: n = (76 - CO_sleeve) / 2 For whole number: CO_sleeve must be even. Let's set: - CO_front = CO_back = 30 (even) - n = (108 - 30) / 2 = 78/2 = 39 increase rounds ✓ - CO_sleeve: n = (76 - CO_sleeve) / 2 → CO_sleeve = 76 - 2×39 = 76 - 78 = -2 That's negative! The sleeve starts with too few sts. The number of increase rounds gives sleeves too many stitches. Problem: sleeves increase at same rate as body sections, but body needs more total increase than sleeves. This is the fundamental constraint of raglan: with 39 increase rounds, sleeves gain 78 sts each. If sleeve at separation = 76, then sleeve CO = 76 - 78 = negative. Impossible. So I need to reduce n, which means adjusting body and sleeve targets. Let me try different approach. Set n = 36 increase rounds. Then: back_sep = CO_back + 72 front_sep = CO_front + 72 sleeve_sep = CO_sleeve + 72 For sleeve_sep = 76: CO_sleeve = 76 - 72 = 4 sts ← very few but okay (some patterns do start with very few sleeve sts) For body: front_sep + back_sep = 216 If CO_front = CO_back: each = (216 - 144) / 2 = 72/2 = 36 sts CO per section Total CO = 36 + 36 + 4 + 4 = 80 sts Neckline = 80/24 × 10 = 33.3 cm (13.1") — a bit small for crew neck. Let me try n = 32: sleeve CO = 76 - 64 = 12 sts ✓ body CO each = (216 - 128) / 2 = 88/2 = 44 sts Total CO = 44 + 44 + 12 + 12 = 112 sts Neckline = 112/24 × 10 = 46.7 cm (18.4") — too large! Let me try n = 34: sleeve CO = 76 - 68 = 8 sts body CO each = (216 - 136) / 2 = 80/2 = 40 sts Total CO = 40 + 40 + 8 + 8 = 96 sts Neckline = 96/24 × 10 = 40 cm (15.75") — perfect for crew neck! Let me verify: - n = 34 increase rounds - CO: Back = 40, Front = 40, each Sleeve = 8 - Total CO = 96 sts ✓ - After 34 increase rounds: - Back = 40 + 68 = 108 ✓ - Front = 40 + 68 = 108 ✓ - Each sleeve = 8 + 68 = 76 ✓ - Total at separation = 108 + 108 + 76 + 76 = 368 sts ✓ - Adding underarm (8 sts each side): - Body: 108 + 108 + 8 + 8 = 232 sts ✓ (= 96 cm finished) - Each sleeve: 76 + 8 = 84 sts ✓ (= 35 cm) **Yoke depth**: 34 increase rounds, every other round, so total rounds in yoke = 34 × 2 = 68 rounds Plus some plain rounds, neckband rounds etc. Yoke depth = 68 rounds / 32 rows per 10 cm × 10 = 21.25 cm That's approximately 21 cm (8.25") — reasonable for armhole depth on size small ✓ **Body length**: From underarm to hem (excluding ribbing): 38 cm (15") Rounds needed = 38 × 32 / 10 = 121.6 → ~122 rounds Hem ribbing: 5 cm = 16 rounds Total body length from underarm: 43 cm (17") including ribbing **Sleeve decreases**: Sleeve starts at: 84 sts Cuff target: 48 sts (20 cm circumference: 48/24×10 = 20 cm ✓) Decreases needed: (84 - 48) / 2 = 18 decrease rounds (each dec round removes 2 sts: k2tog, ssk or equiv) Wait: each decrease round = 2 sts decreased, so 36 sts decreased over 18 dec rounds. 84 - 36 = 48 sts ✓ Sleeve length from underarm to cuff (including cuff ribbing): 45 cm (17.75") Cuff ribbing: 5 cm = 16 rounds Sleeve body: 40 cm = 128 rounds 18 decrease rounds over 128 rounds = every 7 rounds (128/18 = 7.1) → Decrease every 7th round, 18 times: 18 × 7 = 126 rounds — good, close enough, 2 plain rounds extra at top Let me verify: starting at 84 sts, decrease every 7 rounds × 18 times = 84 - 36 = 48 sts ✓ Actually, I want to double-check the "every 7 rounds" fits within the sleeve length: 18 decreases × 7 rounds = 126 rounds + small adjustment at top 126 rounds = 126/32 × 10 = 39.4 cm (15.5") — then add a few plain rounds + 16 ribbing rounds = ~40 + 5 = 45 cm ✓ **Neckband**: CO 96 sts, work k1, p1 rib for 2.5 cm (1") on smaller needles (3.25mm) Join for working in the round after picking up neckband. Actually in top-down, the neckband is worked first, then we transition to body. Let me reconsider. For top-down crew neck: 1. Using smaller needles, CO 96 sts, pm, join for working in the round, work k1, p1 rib for 2.5 cm 2. Change to larger needles 3. Set up raglan: place markers for raglan sections Actually, in many top-down patterns, neckband is CO on circular needle, worked in rib, then markers placed for raglan increases. This is correct. CO 96 sts — this is the neckline cast-on. After neckband, we begin raglan setup. Actually, I should think about whether the neckband sts need adjustment. The CO sts of 96 become the actual working sts. After neckband rib on smaller needles (which has natural negative ease/tighter tension), we switch to larger needles and place markers. Marker setup after neckband: PM, k40 (back), PM, k8 (sleeve), PM, k40 (front), PM, k8 (sleeve) = 96 sts ✓ **Raglan increase setup**: Increase Round: *K to 1 st before marker, M1R, k1, SM, k1, M1L; repeat from * 4 times, k to end. Wait, I need to think about the raglan marker placement. Standard approach: Method 1 (no seam stitch): Place markers between sections. At each marker: M1R before marker, SM, M1L after marker. Method 2 (with 1 seam stitch): Each raglan line = 1 knit stitch. Increases go on either side of that stitch. For easy pattern, I'll use Method 1 (markers only, no seam sts) — but actually Method 2 with a seam stitch makes the raglan line more visible and is considered a nice feature. Let me use 1 seam stitch per raglan line for clarity. With 4 seam sts (one per raglan line): We need to adjust the CO. Let me include 4 seam sts. Revised CO = 96 + 4 = 100 sts? Or adjust sections? Let me keep total CO = 96 and absorb seam sts into the count: Back = 38 sts + 2 seam sts (one each side) Front = 38 sts + 2 seam sts Sleeves = 8 sts (the 4 seam sts are placed on body sections) Hmm, this gets complicated. Let me just go with the clean marker-only method (Method 1). After raglan increase round: Back section increases by 2 (one at each end) Each sleeve increases by 2 Front section increases by 2 So the 34 increase rounds work exactly as calculated. Let me also consider: for an easy pattern, should I include the back neck short rows? The template says "optional." I'll skip them for easy difficulty. **Summary of key numbers for pattern:** Tension: 24 sts × 32 rows = 10 cm Size Small: - Finished bust: 96 cm (38") - Body length underarm to hem: 38 cm (15") + 5 cm (2") ribbing = 43 cm (17") - Sleeve length: 40 cm (15.75") + 5 cm (2") cuff = 45 cm (17.75") - Neckband: 2.5 cm (1") - Yoke depth: approx 21 cm (8.25") Cast on: 96 sts Setup: Back = 40, Sleeve = 8, Front = 40, Sleeve = 8 Raglan increase rounds: 34 After yoke: Back = 108, Front = 108, each Sleeve = 76 Underarm CO: 8 sts each side Final body: 232 sts Final sleeve: 84 sts each Sleeve decrease to: 48 sts Sleeve dec: every 7 rounds × 18 times Needles: - Main: 3.75mm (US 5) circular needle, 80 cm (32") for body - Smaller: 3.25mm (US 3) for ribbing - Also: 3.75mm DPNs or short circular for sleeves Let me also think about what to use for markers. I'll specify stitch markers. For stitch holders: waste yarn or stitch holders. Let me now double-check the ease calculation: Finished bust = 232 sts / 24 sts per 10 cm × 10 = 96.7 cm ≈ 96 cm For size small (34-36" = 86-91 cm), ease = 96 - 88.5 (mid-range) = 7.5 cm ≈ 3" positive ease ✓ Everything checks out. Now I'll write the pattern. One more check — the sleeve seam stitch approach: I'll keep it simple with just markers, no seam stitches, for easy difficulty. The increase round will be: **Raglan Increase Round**: [K to marker, M1L, SM, M1R] 4 times, k to end of round. Wait, let me think about M1L and M1R placement carefully: - M1L before marker = leans left, nice diagonal toward sleeve - M1R after marker = leans right Standard raglan: the increases lean away from the raglan line, creating the diagonal. Standard convention: - K to 1 st before marker, M1R, k1, SM, k1, M1L — when marker is between sections with seam st Without seam st: - K to marker, M1L, SM, M1R — but this creates increases that lean towards each other Actually the conventional approach: K to marker, M1R, SM, M1L — this places: - M1R at the end of one section (leans right) - M1L at the start of next section (leans left) Both sts added to adjacent sections. Hmm, let me think again. In a standard raglan: - The raglan "seam" line is typically at the marker position - On the body side: M1R just before marker (leans right, blends into body sts) - On the sleeve side: M1L just after marker (leans left, blends into sleeve sts) - At the other end of sleeve: M1R just before next marker - Then M1L after next marker (blends into body) So the increase round (without seam sts) is: *K to 1 st before marker, M1R, k1, slip marker, k1, M1L; repeat from * 3 more times, k to end. Wait — this adds 1 st before the marker and 1 st after, but those sts belong to adjacent sections. So effectively: - Each body section grows by 1 st on each end (2 sts per section) - Each sleeve section grows by 1 st on each end (2 sts per section) → Total +8 sts per increase round ✓ But this changes the marker positions slightly... Actually in standard raglan, the markers are placed between sections, and the increases are on either side. The convention: "K to marker, M1R, SM, M1L" — this adds 1 st to the section just ending (body/sleeve) and 1 st to the section just starting. Per traditional raglan instructions: Increase Round: *K to marker, M1R, SM, M1L; rep from * 3 more times, k to end of round. This is clean and easy to follow. Let me use this. Effect: - Round 1 setup: Back(40), M, Sleeve(8), M, Front(40), M, Sleeve(8), M — start of round at beginning of back - After 1 inc round: Back(42), M, Sleeve(10), M, Front(42), M, Sleeve(10), M = 104 sts - After 34 inc rounds: Back(40+68=108), Sleeve(8+68=76), Front(40+68=108), Sleeve(8+68=76) = 368 sts ✓ Great, this is consistent. Now the full pattern is ready to write. **Materials list:** - Sport weight yarn: approximately 1000-1200m for size small - Let me estimate: - Body: 232 sts × 68 body rounds (38cm) = ~15,776 sts worked... - Better to estimate by weight/yardage for sport weight - A typical sport weight sweater size small: ~900-1100m - I'll say approximately 1000 m (1094 yards) **Needles:** - 3.75mm (US 5) circular, 80 cm (32") — main body - 3.25mm (US 3) circular, 80 cm (32") — ribbing - 3.75mm circular or DPNs for sleeves Actually, let me reconsider needle sizes. Sport weight is typically knit on 3.25-3.75mm needles. For tension of 24 sts/10 cm, 3.75mm is reasonable. Let me state this clearly and note to swatch. Now write the pattern!
