Bring the relaxing beauty of the seaside into your home with the Pure Shores Crochet Blanket. Inspired by ocean waves, sandy beaches, summer skies, and deep blue water, this beautiful crochet blanket combines flowing wave texture with a gorgeous sequence of coastal colors.

One of the best things about this pattern is how easily it can be customized. Because the main stitch pattern is built around a multiple of four stitches, you can adjust the width to create anything from a small baby blanket to a generous sofa throw.

The original design also includes helpful photo instructions and a video tutorial, which can be especially useful when learning the unusual wave section for the first time.

Each ball is approximately 50 g / 85 m and the yarn is 100% cotton.

You can, of course, substitute another yarn with a similar weight and choose your own combination of colors.

Crochet Abbreviations

This pattern uses US crochet terminology.

• ch – chain
• ch-sp – chain space
• ss – slip stitch
• sc – single crochet
• dc – double crochet
• hdc – half double crochet
• blo – back loop only
• rep – repeat
• rs – right side
• ws – wrong side
• st/sts – stitch/stitches

Important Pattern Notes

Before beginning, read through the pattern so you are familiar with the wave construction and color changes.

The beginning ch 1 or ch 2 does not count as a stitch. The first dc or hdc is worked into the same stitch as the beginning chain.

The width is based on a multiple of 4 stitches plus 1 stitch in the foundation chain. For the original size, begin with 145 chains.

The unusual wave effect is created by making chain-4 spaces and filling them with groups of seven double crochets. When working Row 5, each new chain-4 section is anchored around the first chain of the previous chain-4 space after turning.

The first chain-4 section is slightly different because it is anchored around the third hdc from the beginning.

Another important detail is the third loop of the half double crochet. This loop is located underneath the stitch, in front of the traditional front and back loops. Working into this loop creates the foundation for the textured wave effect.

When working Row 7, the double crochets from the previous row are positioned behind the raised seven-dc wave sections. Pay close attention to the back loop of the second dc in each seven-dc group and the dc located behind every fourth dc.

Border Tip

For an even distribution of stitches along the long sides during the first border round, the original pattern recommends approximately:

• 9 stitches in the first Yarn A section, including the corner
• 6 stitches in each following color section
• 11 stitches in the final Yarn A section, including the corner

On the opposite long side, reverse this distribution.

144 dc

Rows 8–10

Color Changes

From Rows 11–118, continue repeating Rows 7–10 while changing colors.

The color progression moves upward through the palette from Yarn C to Yarn H, then travels back down through the colors before climbing again.

Follow this general sequence:

C → D → E → F → G → H → G → F → E → D → C → B → A

Then continue upward again:

B → C → D → E → F → G → H

and return through:

G → F → E → D → C → B → A

Continue the four-row repeat until Row 118.

Do not fasten off Yarn A after completing Row 118.

This gradual movement between lighter and darker shades is what gives the finished blanket its beautiful ocean-inspired appearance.

Row 119

Working into the dc of Row 118, repeat:

(3 dc, 1 dc through the blo of the second dc of the dc group and the next dc) 35 times.
