Materials Needed

Before you cast on, gather these supplies to ensure a smooth knitting experience. The pattern calls for worsted weight yarn in four harmonious colors, a circular needle for comfortable stitch capacity, and a few essential tools.

• Yarn: Worsted weight yarn in 4 colors: Deep Teal (A), Seafoam (B), Sandy Beige (C), and Coral (D) – approx. 1200 yds total (e.g., 3 skeins of 400 yds each, or 4 skeins of 300 yds each, depending on your yarn brand).
• Needle: US 8 (5 mm) circular knitting needle, 32-inch cable (to hold all stitches comfortably).
• Notions: Stitch markers (to separate pattern repeats), cable needle, tapestry needle (for weaving in ends), and blocking mats/pins (optional but recommended).
• Gauge: 18 stitches and 24 rows = 4 inches in stockinette stitch. Always knit a gauge swatch to ensure your finished lapghan matches the dimensions.

Step-by-Step Instructions

This pattern is worked in one piece from the bottom up. The stitch pattern is a 24-row repeat that combines cables, bobbles, and ribbing for a rich, tessellated effect. Follow the instructions carefully, using stitch markers to separate the 18-stitch pattern repeats. The finished lapghan measures approximately 36 inches wide by 40 inches long.

Getting Started: Cast On and Border

Cast On: With Color A (Deep Teal), cast on 162 stitches using a long-tail cast on. Place a stitch marker after every 18 stitches to help you track the pattern repeats (you will have 9 full repeats).

Border (Rows 1-8): Work in garter stitch (knit every row) for 8 rows. This creates a clean, sturdy edge that frames the main pattern beautifully.

Finishing Touches: Border and Bind Off

Border (Rows 1-8): With Color A, work in garter stitch (knit every row) for 8 rows. This mirrors the bottom border and frames the pattern symmetrically.

Bind Off: Bind off all stitches loosely in knit. To avoid a tight edge, use a needle one size larger for the bind-off or bind off with a relaxed tension.

Finishing: Weave in all ends with a tapestry needle, being careful to secure them within the same color sections to keep the back neat. Block the lapghan gently by wetting it and pinning it to the desired dimensions (36x40 inches). This step is crucial to open up the cable patterns and even out the bobbles, giving your throw a professional, polished look.

Once dry, your Tidepool Tessellation Throw is ready to drape over a favorite chair, snuggle under on a cool evening, or gift to someone special. The combination of cables and bobbles creates a fabric that is both visually intriguing and wonderfully cozy. Enjoy the process, and let the rhythm of the stitches bring you the same calm as a gentle ocean wave.
