Project introduction

The Sea Glass Throw is a lap blanket sized for the end of a couch, and this page is an overview rather than a full tutorial. It summarizes the design, materials, construction, stripe plan, sizing logic, color changes, and optional border. For the complete directions, use the Original designer’s pattern and instructions from Daisy Cottage Designs.
The blanket name came from beach and wave suggestions offered by the designer’s Instagram followers. The fabric uses only a few basic stitches, stays mostly in double crochet, and is meant to give beginners clear texture with good drape. The source presents it as an easy project and a thoughtful gift for yourself or a friend.
Any worsted weight yarn can be used. The source suggests soft acrylic or 100 percent cotton for blankets. The web version is free, while the print-friendly PDF sold on Etsy is paid.
Materials
Gather the sample supplies before starting, especially if you want the same color flow and finishing. The list below follows the sample blanket exactly. If you substitute yarn, choose another worsted weight yarn that gives a fabric you like.
- J/10 crochet hook, 6.00 mm
- Approximately 1600 yards of worsted weight yarn
- Premier Anti Pilling Every Day Worsted: Spa, 5 skeins; Meadow, 3 skeins; Snow White, 2 skeins
- Each sample skein: 3.5 oz and 180 yards
- Tapestry needle and scissors for weaving ends
Pattern Notes

The finished blanket measures approximately 37 inches by 52 inches. The source also says other sizes are included. The stitch multiple is 4+2, and fuller size adjustment guidance appears at the end of the pattern. Do not work into the top of the turning chain.

The Sea Glass Throw: An Easy Lap Blanket Crochet Pattern Overview

The sample starts in Spa with a chain of 130. The foundation row is worked in single crochet across the chain, giving a stated total of 129 single crochet stitches. Then the pattern turns and builds its texture with double crochet and grouped stitches.
Row 1 places double crochet at the start and end, with grouped (2 dc, ch 1, 2 dc) stitches worked between skipped stitches. Row 2 works those grouped stitches into each chain 1 space across, again framed by double crochet at the edges. Rows 3 through 90 repeat Row 2, which builds the open texture and drape.
The stripe plan uses Spa, White, and Meadow. It repeats a stripe block made of 5 rows Spa, 1 row White, 2 rows Meadow, 3 rows Spa, 4 rows Meadow, and 2 rows White, then the source closes the sample with 5 rows of Spa. For a visual start, see the video tutorial.
How to Change Colors

Work the color change during the last stitch of the row. Stop before pulling the old working yarn through the final two loops of the last double crochet. Place the new yarn on the hook and pull it through those last two loops, so the new color closes the stitch. Leave a long tail on both the old and new colors for weaving in later.
The source also mentions a video tutorial for this technique, which can help if the written description feels unclear.
Adjusting the Size of This Lap Blanket Crochet Pattern Overview


For a custom width, chain in multiples of 4 until the blanket is as wide as you want, then add 2 more chains. The source example is 32 times 4 equals 128, and 128 plus 2 equals 130. This keeps the stitch repeat aligned across the row.
To preserve the stripe pattern, keep the row count in multiples of 17 plus 5. The source example is 17 times 5 equals 85, and 85 plus 5 equals 90. Each set of 17 adds about 9 inches, while the final 5 rows add just under 3 inches.
Repeat the stripe block as often as you like, then finish with 5 rows of Spa. The simple stripes also make it easy to keep the sample colors or choose your own palette.
Optional Border Construction Overview (not shown)
The optional border is worked in three rounds and was not shown in the source photos. Round 1 uses Spa and single crochet evenly around the blanket, with 3 single crochet in each corner, then joins with a slip stitch. Cut the yarn and weave in the ends.
Round 2 joins Meadow, chains 1, and works half double crochet evenly around, with half double crochet, chain 2, half double crochet in each corner, then joins with a slip stitch. Cut the yarn and weave in the ends.
Round 3 joins Snow White, chains 2, and works double crochet around, with double crochet, chain 2, double crochet in each corner, then joins with a slip stitch. Cut the yarn and weave in the ends.
