Materials Needed

Before you begin, gather the following supplies to ensure a smooth and enjoyable crocheting experience. The Isla Vest is designed to be lightweight and breathable, making yarn choice crucial for the perfect drape.

• Yarn: Lion Brand Comfy Cotton Blend (or any light worsted weight cotton blend) in 3 colors:
  • Sand (Color A) – approx. 150g
  • Pebble (Color B) – approx. 125g
  • Driftwood (Color C) – approx. 125g
  Total approx. 400g. The cotton blend ensures breathability and stitch definition.
• Crochet Hook: 5.5mm hook (US I-9)
• Other Tools: Yarn needle for weaving in ends, scissors, and blocking mats with pins (for finishing).
• Gauge: 14 sts x 8 rows = 4 inches in shell stitch pattern (after blocking). Always check your gauge to ensure the correct finished size.

Step-by-Step Instructions

This pattern is worked in flat panels from the bottom up, then seamed together. The construction is straightforward, and the color changes create a beautiful, subtle gradient effect. Follow these detailed instructions carefully to achieve the perfect fit and finish.

Understanding the Pattern

Sizes: S/M (M/L) – Finished chest circumference: 36 (40) inches, length: 22 (24) inches. Instructions are written for the smallest size with the larger size in parentheses.

Special Stitches:

• Shell (sh): Work 5 double crochet (dc) stitches into the same stitch.
• Picot (p): Chain 3 (ch 3), then slip stitch (sl st) into the 3rd chain from the hook.

Important Notes: The vest is worked in two main panels (back and front), then seamed at the shoulders and sides. The color sequence is crucial: you will work 2 rows in Color A, then 2 rows in Color B, then 2 rows in Color C, and repeat this sequence throughout the entire body of the vest.

Back Panel

Foundation: With Color A, chain 92 (102).

Row 1 (Right Side): Work 1 dc into the 4th chain from the hook. *Skip 2 chains, work a shell (5 dc) into the next chain, skip 2 chains, work 1 dc into the next chain. Repeat from * across the row. Turn. You should have 15 (17) shells.

Row 2: Chain 3 (counts as first dc), work 1 dc into the same stitch as the chain 3. *Work a shell into the center dc of the next shell from the previous row, then work 1 dc into the next dc (the single dc between shells). Repeat from * across, ending with 2 dc worked into the last stitch. Turn.

Pattern Repeat: Repeat Row 2 for the pattern. Follow the color sequence strictly: 2 rows in Color A, 2 rows in Color B, 2 rows in Color C. Continue this pattern until the piece measures 20 (22) inches from the start, ending with a Wrong Side (WS) row.

Shape Shoulders:

• Right Shoulder: On the next Right Side (RS) row, work across the first 5 (6) shells only. Turn, leaving the remaining stitches unworked. Work 2 more rows on these stitches only, then fasten off.
• Neck: Return to the center of the work. Skip the next 5 (5) shells for the neck opening. Join the yarn with a slip stitch in the next stitch, and work across the last 5 (6) shells for the left shoulder. Work 2 rows on these stitches, then fasten off.

Front Panels (Make Two)

These pieces are identical and form the two open fronts of the vest.

Foundation: With Color A, chain 46 (51).

Row 1: Work 1 dc into the 4th chain from the hook. *Skip 2 chains, work a shell into the next chain, skip 2 chains, work 1 dc into the next chain. Repeat from * across. Turn. You should have 7 (8) shells.

Pattern: Work in the same pattern as the back panel, following the exact same color sequence (2 rows A, 2 rows B, 2 rows C). Continue until the piece measures 16 (18) inches from the start, ending with a WS row.

Shape Neck: At the neck edge (this will be the left side for the right front piece, and the right side for the left front piece), you will decrease 1 shell every row for 4 rows. To do this, work 2 dc together at the neck edge instead of working a full shell. After completing the 4 decrease rows, continue working even on the remaining stitches until the piece matches the length of the back shoulder. Fasten off. Repeat this entire process for the second front piece.

Finishing and Assembly

Seaming: Sew the shoulder seams together using a yarn needle and a whip stitch or mattress stitch. Then, sew the side seams, leaving the top 8 (9) inches open on each side for the armholes.

Edging: With Color A, work a round of single crochet (sc) evenly around the entire outer edge of the vest. This includes the armholes, the front edges, and the bottom hem. Join with a slip stitch to the first sc.

Picot Trim: On the next round, work *1 sc in the next stitch, work a picot (ch 3, sl st in 3rd ch from hook) in the next stitch. Repeat from * around the entire edge. Fasten off.

Final Steps: Weave in all loose ends carefully with your yarn needle. Block the vest to the specified measurements to open up the shell stitches and give it a professional, polished finish. Lay it flat on blocking mats, pin to size, and spray with water. Allow it to dry completely before wearing.
