🧵 Construction Overview:
This cardigan is worked top-down, using a raglan yoke, then split into body and sleeves.
🧷 Instructions:
Step 1: Yoke (Top part)
- Foundation Chain:
Ch 54 (this will form the neck) - Row 1 (Setup):
Dc in 4th ch from hook, dc in next st until end. You should have 52 dc. Turn. - Row 2 (Raglan increases):
You will now place 4 markers for raglan increase points.
Example placement:- 8 dc (left front), mark next st
- 10 dc (sleeve), mark next
- 16 dc (back), mark next
- 10 dc (sleeve), mark next
- 8 dc (right front)
Dc to marker, 2dc in marked st, move marker, repeat
- Repeat Row 2 for 7–9 rows (until yoke depth is about 4.5–5 inches)
Step 2: Split for Sleeves
- When yoke is long enough, you’ll separate sleeves:
- Body Row:
Dc to first marker, skip sleeve sts, ch 4 (armhole), dc across back to next marker, skip next sleeve sts, ch 4, dc to end. You now have a body opening with 2 armholes.
Step 3: Body
- Work in rows below armholes in dc.
- Continue for 6–8 rows (or until desired length).
- Optional: Add shell stitch edging at bottom.

Step 4: Sleeves
- Attach yarn at underarm.
- Dc around sleeve opening, join.
- Work 5–6 rounds.
- Finish with a simple sc or shell border.
Step 5: Front Edging
- Attach yarn at the bottom corner of one front panel.
- Sc evenly up the edge, around the neckline, and down the other side.
- Optional: Add buttonholes every 5–6 stitches on one side (use ch 2, skip 2 sts method).
- Add buttons on the opposite side.
✅ Finishing Touches:
- Weave in all ends with yarn needle.
- Sew buttons if used.
- Lightly block the cardigan for a neat finish.
🎨 Customization Ideas:
