Step-by-Step Instructions

Bodice

The bodice is worked as a flat piece and then divided for legs.

1. Foundation Chain: Ch 62. (62 sts)
2. Row 1: Sc in the 2nd ch from hook and in each ch across. (61 sc)
3. Row 2: Ch 3 (counts as dc), turn. *Skip 2 sc, in next sc work Wave Stitch (1dc, 1tr, 1dc); rep from * to end, finish with 1 dc in last sc. (20 waves + 1 dc)
4. Row 3: Ch 1, turn. Sc in each stitch across. (61 sc)
5. Rows 4–12: Repeat Rows 2–3 for a total of 5 wave pattern repeats, ending with Row 3.

Legs

The legs are worked separately from the bodice. 6. Divide for Legs: Split the bodice with 24 stitches for the left leg, 13 stitches for the body, and 24 stitches for the right leg.

Left Leg: 7. Row 1: Ch 1, turn. Work in sc across the left 24 sts. (24 sc) 8. Row 2: Ch 3, turn. Work Wave Stitch across. (8 waves) 9. Rows 3–5: Repeat Rows 1–2 for continuing rows. At the end of Row 5, fasten off. (24 sts)

Right Leg (Repeat the same as Left): 10. Row 1: Ch 1, turn. Work in sc across the right 24 sts. (24 sc) 11. Row 2: Ch 3, turn. Work Wave Stitch across. (8 waves) 12. Rows 3–5: Repeat Rows 1–2 for continuing rows. At the end of Row 5, fasten off. (24 sts)

Assembly

This step joins all the parts together. 13. Join the Shoulders: Align the front and back bodice sections, using whip stitch or slip stitch to sew the shoulder seams. 14. Seam the sides: Starting from the bottom of the legs, sew up to the underarm area on both sides of the romper, leaving spaces for the armholes. Use a mattress stitch for a neat finish. 15. Edges: Optionally, add a round of sc around the armholes and leg openings for a clean look.

Beginner Tips for a Neat Romper

• Use stitch markers to keep track of your rows and sections.
• Count your stitches regularly to avoid mistakes.
• Keep an even tension for consistent stitch size across your project.

Common Mistakes (and How to Fix Them)

• "My stitches are too tight." – This could mean your tension is too tight; try using a larger hook size.
• "The leg openings are too small." – Make sure to count your rows correctly; you may need to adjust the row count for a larger size.
• "My waves don't look even." – Ensure you’re following the wave stitch pattern carefully and check you’re not skipping any stitches.

FAQ

How do I change the size of the romper?
