Foundation

With Color A (Sand), cast on 226 stitches loosely. Work 6 rows in garter stitch (knit every row) for a sturdy, clean edge that will anchor your blanket beautifully.

Main Body – Section by Section

Section 1 (Sand)

Continue with Color A. Work the Pebble Stitch pattern (Rows 1-6) for 20 rows total (about 3.5 inches). This creates the first band of textured "pebbles" reminiscent of warm beach sand.

Section 2 (Seafoam)

Switch to Color B. Work in stockinette stitch (knit RS, purl WS) for 12 rows. On the 6th row, create a subtle wave effect:

Row 6 (RS): *K10, Yo, K2tog, K8; repeat from * to end.

This delicate eyelet row adds gentle ripples like water washing over the shore. Complete the remaining 6 rows in plain stockinette.

Section 3 (Driftwood)

Switch to Color C. Work the Pebble Stitch pattern for 24 rows (about 4 inches). The deeper, earthier tone of driftwood adds grounding contrast to the lighter sections.

Section 4 (Pearl)

Switch to Color D. Work in a simple seed stitch for 16 rows:

• Row 1: K1, P1; repeat to end.
• Row 2: P1, K1; repeat to end.

This nubby, scattered texture evokes fine sand and adds lovely visual interest.

Section 5 (Repeat Sand)

Switch back to Color A. Work the Pebble Stitch pattern for 20 rows.

Section 6 (Repeat Seafoam)

Switch to Color B. Repeat the wave stockinette section exactly as before (12 rows with the eyelet row on row 6).

Section 7 (Repeat Driftwood)

Switch to Color C. Work the Pebble Stitch pattern for 24 rows.

Section 8 (Repeat Pearl)

Switch to Color D. Work seed stitch for 16 rows.

Continue Alternating Sections

Keep alternating the sections in this order (Sand, Seafoam, Driftwood, Pearl) until your blanket measures approximately 58 inches from the cast-on edge. For a balanced, symmetrical look, end with a Sand section (Pebble Stitch).

Border

With Color A, work 6 rows of garter stitch across all stitches. This clean, sturdy border frames your blanket beautifully and prevents curling.

Bind off loosely in knit to maintain the drape and flexibility of the edge.

Finishing

1. Weave in all ends with your tapestry needle, being careful to secure them discreetly within the stitches.
2. Block the blanket gently to open up the stitches and even out the texture. This step is essential for achieving that beautiful, professional finish.
3. Lay flat to dry completely before using or folding.

Optional: Boho Fringe

For an extra beachy, bohemian feel, add a simple fringe along the cast-on and bind-off edges. Cut strands of Color A and Color C yarn to your desired length (about 8-10 inches), fold each strand in half, and pull the loop through the edge stitches using a crochet hook. Pull the ends through the loop and tighten. Space fringe every 2-3 stitches for a full, textured look.

Tips for Success

• Keep your tension consistent throughout the project. Cotton yarn has less give than wool, so maintain a relaxed but even grip.
• Count your stitches regularly, especially when working the Pebble Stitch pattern, to catch any mistakes early.
• Use stitch markers between sections to easily track where you are in the pattern.
• Blocking is crucial for cotton—it helps the stitches relax and creates that beautiful, even drape.

The Tidal Drift Beach Throw Blanket is more than just a knitting project—it's a journey to the coast, one stitch at a time. The rhythmic repetition of the pebble stitch, the gentle waves of the eyelet rows, and the soothing color palette combine to create a truly special piece you'll treasure for years to come.

Whether you gift it to a beach lover or keep it for yourself, this throw brings a piece of the shoreline into any home. Happy knitting, and may your stitches always feel like gentle waves!
