Planning

1. **Design Strategy**: - User requests: in the round, bottom up, 180 stitches to start, beginner level - Template shows flat construction, but user specifically wants in the round (seamless) - Adaptation needed: Convert flat template to circular construction - Will use crew neck (simpler than V-neck for beginners) - Worsted weight yarn, beginner-friendly stockinette with ribbed edging - 180 stitches suggests approximately 36" circumference at 5 sts/inch gauge 2. **Construction Plan**: - Cast on 180 stitches, join in the round - Work ribbed hem in the round - Continue in stockinette stitch (knit every round) to armholes - Divide for front and back (90 stitches each) - Work front and back separately flat (with bind-offs for armholes and neck shaping) - Join shoulders with three-needle bind-off or seaming - Pick up and work armhole edging in the round - Pick up and work neckline edging in the round - Size: approximately adult medium/large based on 36" chest 3. **Quality Assurance**: - Potential issues: Transition from circular to flat at armholes (clear instructions needed) - Neck shaping must be centered and symmetrical - Armhole depth should be adequate for comfort (9-10 inches standard) - Beginner concerns: Clear marking for beginning of round, joining carefully without twisting - Ensure pick-up rates are even and create clean edges 4. **Final Calculations**: - Standard worsted gauge: 5 sts/inch, 7 rows/inch on US 7 needles - 180 stitches รท 5 sts/inch = 36" circumference (18" wide when flat) - Front and back: 90 stitches each = 18" wide - Ribbing: 2x2 rib (divisible by 4; 180รท4=45, perfect) - Body length to armhole: ~14" for standard fit - Armhole depth: ~9.5" - Total length: ~23.5"

## PATTERN INSTRUCTIONS

### BODY

**Cast On and Ribbing**

Using longer circular needle, cast on 180 stitches. [CHECK: 180 รท 4 = 45, evenly divisible for 2x2 rib โœ“]

Place marker and join to work in the round, being careful not to twist stitches. The marker indicates the beginning of the round and the left side "seam."

**Setup Round**: K90, pm (this marks right side "seam" and division between front and back), k90 to end of round. 
[CHECK: 90 + 90 = 180 sts โœ“]

**Ribbing Round**: *K2, p2; repeat from * to end of round.

Repeat Ribbing Round for 2.5" (6.5 cm) total, approximately 18 rounds.

**Body**

**Knit every round** (stockinette stitch) until piece measures 14" (35.5 cm) from cast-on edge, or desired length to armhole.

### DIVIDE FOR FRONT AND BACK

**Next Round**: Remove beginning-of-round marker. K4, bind off next 8 stitches (removing side marker when you reach it), k until 4 stitches remain before next marker, bind off next 8 stitches (removing marker), knit to end.
[CHECK: 90 - 8 = 82 sts for back; 90 - 8 = 82 sts for front โœ“]

You will now have two separate sections:
- **Back**: 82 stitches
- **Front**: 82 stitches

Place front stitches on scrap yarn or stitch holder. You will work the back first.

### BACK

Working back and forth in rows on the 82 back stitches:

**Row 1 (WS)**: Purl.
**Row 2 (RS)**: Knit.

Repeat Rows 1-2 (stockinette stitch worked flat) until armhole measures 8.5" (21.5 cm) from bind-off, ending with a WS row.

**Shape Back Neck**

**Next Row (RS)**: K27, bind off center 28 stitches, k27.
[CHECK: 27 + 28 + 27 = 82 sts โœ“]

You now have two shoulders with 27 stitches each. Place the stitches for one shoulder on a holder and work the other shoulder first.

**Left Shoulder**:
Working on the first 27 stitches only:

**Next Row (WS)**: Purl.
**Next Row (RS)**: Ssk, knit to end. (26 sts remain)
**Next Row (WS)**: Purl.

Place remaining 26 stitches on holder for shoulder.

**Right Shoulder**:
Return to the 27 stitches for the right shoulder, ready to work a WS row.

**Next Row (WS)**: Purl.
**Next Row (RS)**: Knit to last 2 sts, k2tog. (26 sts remain)
**Next Row (WS)**: Purl.

Place remaining 26 stitches on holder for shoulder.

Back armhole depth is approximately 9.5" (24 cm).

### FRONT

Return to the 82 front stitches. Attach yarn, ready to work a WS row.

**Row 1 (WS)**: Purl.
**Row 2 (RS)**: Knit.

Repeat Rows 1-2 until armhole measures 6" (15 cm) from bind-off, ending with a WS row.

**Shape Front Neck**

**Next Row (RS)**: K32, bind off center 18 stitches, k32.
[CHECK: 32 + 18 + 32 = 82 sts โœ“]

You now have two sides with 32 stitches each.

**Left Front Neck**:
Working on the first 32 stitches only:

**Row 1 (WS)**: Purl.
**Row 2 (RS)**: Knit to last 2 sts, k2tog. (31 sts)
**Row 3**: Purl.

Return to the 32 stitches for right front neck, ready to work a WS row.

**Row 1 (WS)**: Purl.
**Row 2 (RS)**: Ssk, knit to end. (31 sts)
**Row 3**: Purl.
**Row 4**: Ssk, knit to end. (30 sts)

### JOIN SHOULDERS

Using three-needle bind-off or your preferred seaming method, join the front and back at each shoulder. Match the 26 held stitches from front left shoulder with 26 held stitches from back left shoulder; repeat for right shoulder.
[CHECK: 26 = 26 sts for each shoulder โœ“]

### ARMHOLE EDGING

With RS facing and using DPNs or shorter circular needle, beginning at center of underarm bind-off:

Pick up and knit 4 stitches along underarm bind-off, pick up and knit approximately 68 stitches evenly around armhole edge to other side of underarm, pick up and knit remaining 4 stitches along underarm bind-off. (approximately 76 stitches total)
[NOTE: Adjust to a multiple of 4 for 2x2 rib. Use 76 or 80 sts as needed for even ribbing.]

If you have 76 sts: Adjust to 76 sts (already a multiple of 4 โœ“)
If you have a different number, adjust to the nearest multiple of 4 by picking up slightly more or fewer stitches along the armhole edges.

Place marker and join to work in the round.

**Ribbing Round**: *K2, p2; repeat from * to end.

Repeat Ribbing Round for 1" (2.5 cm), approximately 7 rounds.

Bind off in pattern.

Repeat for second armhole.

### NECKLINE EDGING

With RS facing and using 16" circular needle (or longer needle with magic loop), beginning at left shoulder seam:

Pick up and knit approximately 15 stitches down left front neck edge, 18 stitches across front neck bind-off, 15 stitches up right front neck edge, 2 stitches down right back neck edge, 28 stitches across back neck bind-off, and 2 stitches up left back neck edge. (80 stitches total)
[CHECK: 15 + 18 + 15 + 2 + 28 + 2 = 80 sts, divisible by 4 โœ“]

Place marker and join to work in the round.

**Ribbing Round**: *K2, p2; repeat from * to end.

Repeat Ribbing Round for 1" (2.5 cm), approximately 7 rounds.

Bind off in pattern.

### FINISHING

Weave in all ends. Block to finished measurements.

## CUSTOMIZATION OPTIONS

**Length**: Adjust body length before dividing for armholes. Add or subtract rows as desired.

**Neckline**: For a deeper V-neck, begin front neck shaping earlier and bind off fewer center stitches.

**Pockets**: Add patch pockets by working separate rectangular pieces and seaming to front.

**Stripes**: Work in stockinette with color changes every few rounds or rows for a striped effect.
