Materials Needed

Before you begin your crochet journey, gather the following materials:

• Yarn: Worsted weight cotton blend yarn in 4 shades – Seafoam (A), Aqua (B), Deep Teal (C), Navy (D) – approximately 1200g total (300g of each color). A cotton blend provides excellent stitch definition and breathability, perfect for this coastal-inspired design.
• Hook: 5.5mm (I-9) crochet hook
• Notions: Stitch markers, tapestry needle for weaving in ends and seaming
• Gauge: 14 stitches x 10 rows = 10 cm in wave stitch pattern (blocked). Always check your gauge to ensure proper fit!

Sizes & Measurements

This pattern is written for sizes S (M, L, XL) with finished chest measurements of 96 (106, 116, 126) cm. The relaxed, boxy fit means you can choose a size based on your actual chest measurement for a comfortable, oversized look, or size down for a closer fit.

Stitch Abbreviations

• ch = chain
• sc = single crochet
• dc = double crochet
• sl st = slip stitch
• st(s) = stitch(es)
• sk = skip
• rep = repeat
• RS = right side
• WS = wrong side

Special Stitch – Wave Cluster (WC)

Work 3 dc into the same stitch, skip 2 stitches, sc into next stitch. This creates a gentle wave peak that forms the beautiful textured pattern.

Pattern Notes

The sweater is worked in 4 panels (front, back, two sleeves) from the bottom up, then seamed together. The wave stitch pattern is a multiple of 6 + 2 stitches. Color changes occur every 10 rows, creating distinct horizontal bands that transition from seafoam to navy.

Step-by-Step Instructions

BACK PANEL

Foundation: With color A (Seafoam), chain 74 (82, 90, 98).

Row 1 (RS): Sc in 2nd ch from hook, *sk 2 ch, WC across (3 dc in next ch, sk 2 ch, sc in next ch)*, rep from * to end, turn. You will have 12 (13, 14, 15) wave clusters.

Row 2: Ch 1, sc in first st, *sk 2 sts, WC across (3 dc in next st, sk 2 sts, sc in next st)*, rep from * to end, turn.

Continue: Repeat Row 2 for the wave pattern. Work 10 rows in color A, then switch to color B (Aqua) for 10 rows, then color C (Deep Teal) for 10 rows, then color D (Navy) for 10 rows. Continue alternating colors every 10 rows until the piece measures 40 (42, 44, 46) cm from the start, ending with a WS row.

Armhole Shaping

Next row (RS): Sl st over the first 6 sts, ch 1, sc in same st, continue wave pattern across until 6 sts remain, turn. This decreases 6 stitches on each side.

Continue in pattern on the remaining 62 (70, 78, 86) sts until the armhole measures 20 (21, 22, 23) cm. Fasten off.

FRONT PANEL

Work the same as the back panel until the armhole shaping is complete. Continue in pattern until the armhole measures 15 (16, 17, 18) cm, ending with a WS row.

Neck Shaping

Next row (RS): Work in pattern across the first 22 (25, 28, 31) sts, turn, leaving the remaining sts unworked. Decrease 1 st at the neck edge every row 4 times. Work even on the remaining 18 (21, 24, 27) sts until the armhole matches the back panel. Fasten off.

Return to the unworked sts. Skip the center 18 (20, 22, 24) sts, join yarn, work pattern across the remaining sts, and decrease at the neck edge 4 times. Work even to match the other side. Fasten off.

SLEEVES (make 2)

Foundation: With color A, chain 38 (38, 44, 44).

Work the wave pattern as for the back panel, increasing 1 st at each edge every 6 rows (by working 2 sc in the first and last st) until you have 62 (66, 72, 76) sts. Work even until the sleeve measures 45 (46, 47, 48) cm. Fasten off.

FINISHING

Sew the shoulder seams, side seams, and sleeve seams using your tapestry needle and matching yarn. Set in the sleeves, matching the armhole edges carefully. Weave in all loose ends.

Neckband

With color A, join yarn at the shoulder seam. Work 1 round of sc evenly around the neck opening, then 1 round of reverse sc (crab stitch) for a neat, polished edge. Fasten off and weave in ends.

Blocking

Block the sweater to the specified measurements. This is crucial for the wave stitch to open up and lay beautifully. Pin the sweater to a flat surface, mist with water, and allow to dry completely. The cotton blend will relax and drape beautifully after blocking.

Pro Tips for Success

• Count your stitches at the end of each row, especially during the first few rows of the wave pattern, to ensure your clusters align correctly.
• Use stitch markers at the armhole shaping points to keep track of your decreases.
• Keep your tension consistent – the wave stitch looks best when the dc clusters are worked evenly.
• Block before seaming if possible, as this makes the pieces easier to align and sew together neatly.

Your Tidal Drift Sweater will become a cherished wardrobe staple – a wearable piece of shoreline serenity that captures the beauty of the ocean in every stitch. The gradient color transitions create a stunning ombré effect that's sure to draw compliments wherever you go. Happy crocheting!
