Do the math
The examples use the gauge above. Put your own swatch into the gauge calculator first, then use your numbers in each formula.
| Step | Formula | Example | Tool |
|---|---|---|---|
| Back | (chest + 2 in) ÷ 2 × sts per in | 10 × 5.5 = 55 sts | Cast-On Calculator |
| Body to underarm | chart back waist length + 2.5 in − sleeve depth | 7.5 + 2.5 − 4 = 6 in (66 rows) | Size Charts |
| Sleeve cast-on | chart sleeve length × sts per in | 7.5 × 5.5 = 41 sts each side | By hand |
| Sleeve depth | (upper arm + ease) ÷ 2 | about 4 in (44 rows) | By hand |
| Back neck | about 4 in, odd | 21 sts, leaving 58 each side | By hand |

Instructions
Back
Cast on the back count (example: 55). Knit until it measures the body-to-underarm figure (example: 66 rows).
Sleeves
Using the knitted or cable cast-on, cast on the sleeve count at the start of the next 2 rows (example: 55 + 82 = 137 sts). Knit the sleeve depth (example: 44 rows).
Neck
Next row (RS): K58, bind off 21, k58. Work each side separately from here.
Fronts (both alike, mirrored)
Knit 2 rows. Neck increase: On the next 12 RS rows, knit to the neck edge and M1 1 st in from the edge (example: 58 → 70).
Knit until the front sleeve depth matches the back (example: 44 rows from the shoulder).
Bind off the sleeve sts (41) at the sleeve edge. Knit the remaining front (29) until it matches the back length. Bind off.
Finishing
- Fold at the shoulders. Seam each sleeve underside and side in one line.
- Ties: knit two 3-st I-cords, 8 in (20 cm) long. Sew one to each front edge at the underarm.
- Weave in ends.
Designer’s notes
- Safety: keep ties short and never leave a sleeping baby in anything with ties.
- Roll the cuffs back for growing room: add 1 in to the sleeve cast-on.
