🪡 Construction Overview
This sweater is crocheted from the top down in one piece with raglan increases, creating the yoke, then separating for sleeves and continuing the body in rounds. Sleeves are added at the end. You can customize the neckline (button placket, collar, or hood) if desired.
🧶 Step-by-Step Instructions
1. Starting the Yoke (Top Down)
Foundation Chain:
Ch 56 and join with sl st to form a circle. (Ensure the chain is not twisted.)
Row 1 (Setup Row):
Ch 2 (counts as hdc), hdc in each ch around. Join with sl st to top of ch-2. (56 hdc)
Now mark the raglan increase points:
- Place markers after st 9, 18, 38, and 47
- This separates: 9 (front), 9 (sleeve), 20 (back), 9 (sleeve), 9 (front)
2. Yoke Increases (Raglan Style)
You will increase at 4 points every other round.
Row 2–10:
- Ch 2, hdc in each st across
- At each marker, do: hdc, ch 1, hdc (this creates the raglan increase)
- Move the markers up to the ch-1 spaces each row
At the end of Row 10, you should have:
- 27 sts front, 16 sts each sleeve, 27 sts back = 86 hdc total
Try it against baby measurements or check stitch counts.
3. Divide for Body and Sleeves
Row 11:
Ch 2, hdc across front stitches, skip sleeve sts, ch 4 (underarm), hdc across back, ch 4, skip other sleeve sts, hdc to end. Join with sl st.
Now you are working the body in the round.
4. Body of the Sweater
Row 12–24 (or desired length):
Ch 2, hdc in each stitch and ch across (front, back, and underarms).
Join each round with sl st.
Optional finishing row: Do 1 row of sc for a clean hemline.
Fasten off and weave in ends.
5. Sleeves
Rejoin yarn at armhole underarm.
Round 1:
Attach yarn, ch 2, hdc evenly around armhole (approx. 30–32 sts), including the underarm chains.
Rounds 2–12 (or desired length):
Hdc around in continuous rounds or join each round with sl st.
Optional: Decrease 2 sts every 3rd row for tapered sleeves.
Final row: One round of sc for clean edging.
Repeat for the other sleeve.
6. Neckline Finishing
You can customize the neckline in multiple ways:
Option 1: Ribbed Collar
Attach yarn at neckline, work 2–3 rounds of sc or hdc, or do front post/back post dc for ribbing.
Option 2: Buttoned Placket
If you want a V-neck or crew with buttons:
- Do not join foundation chain in a circle. Work in rows for 2–3 inches.
- Then join to continue in the round.
- Later, work a button band on each side (3 rows of sc) and sew on buttons.
🎨 Customization Ideas
- Add stripes in contrasting colors
- Sew on a crochet applique (e.g., star, bear, initials)
- Use variegated yarn for fun color changes
- Add a hoodie for a modern twist
🧼 Care Instructions
Machine wash gentle (if using acrylic or cotton-blend yarn), or hand wash with mild soap. Lay flat to dry to maintain shape.
📝 Tips for Success
- Always check gauge with a swatch (should be about 14–16 hdc in 4″)
- Use stitch markers generously to keep track of raglan increases and sleeve joins
- Keep yarn tension consistent for a neat finish
- Try the garment on a baby mannequin or lay flat against baby clothes for sizing
