Materials Needed

Before you begin, gather the following supplies. Using the recommended materials will ensure your gauge matches and your blanket achieves that perfect, plush drape.

• Yarn: DK weight (#3 light) cotton or bamboo blend yarn – approximately 1200 yards total. The pattern uses two colors: Color A (Seafoam) and Color B (Sand). A great example is Lion Brand Coboo in 'Seafoam' and 'Sand'. You will need roughly 600 yards of each color.
• Crochet Hook: 5.0 mm (H-8) crochet hook. A comfortable ergonomic hook is recommended for extended crochet sessions.
• Other Tools: Yarn needle for weaving in ends, scissors, and stitch markers (optional, but helpful for keeping track of rows).

Gauge

14 stitches and 10 rows = 4 inches in half double crochet. Always make a gauge swatch before starting to ensure your finished blanket is the correct size. If your gauge is too loose, try a smaller hook; if it's too tight, try a larger hook.

Step-by-Step Instructions

This pattern is worked in rows, creating a beautiful, reversible texture. The key is to place your shells in the "valleys" of the previous row to create the wave effect. Follow these instructions carefully, and you'll be amazed at how quickly the pattern comes together.

Foundation & Row 1

Foundation: With Color A (Seafoam), chain 121 loosely. This creates a foundation that will result in a blanket approximately 36 inches wide. Ensure your chain is not twisted before beginning Row 1.

Row 1: Work 1 single crochet (sc) in the 2nd chain from your hook, and in each chain across. Turn. You should have a total of 120 sc stitches. This row creates a solid, stable base for your wave pattern.

Row 2: Creating the First Shells

Row 2: Chain 1 (this does not count as a stitch), sc in the first stitch. *Skip the next 2 stitches, work 5 double crochet (dc) in the next stitch (this forms your "shell"), skip the next 2 stitches, sc in the next stitch. Repeat from * across the row, ending with a sc in the very last stitch. Turn. (You will have 20 shells).

Pro Tip: The single crochet between shells acts as the anchor point for the next row's shell, creating the wave illusion.

Row 3: Building the Wave

Row 3: Chain 3 (this counts as your first double crochet), work 2 dc in the very first stitch (the same stitch you just chained from). *Skip the next 2 stitches, sc in the next stitch (this should be the center dc of the shell from the previous row), skip the next 2 stitches, work 5 dc in the next stitch (the sc from the previous row). Repeat from * across the row, ending with 3 dc in the very last stitch. Turn.

Key Detail: Notice how you are now working your new shell into the single crochet of the previous row, and your single crochet into the center of the previous shell. This offset is what creates the beautiful, rhythmic wave pattern.

Row 4: Continuing the Rhythm

Row 4: Chain 1, sc in the first stitch. *Skip the next 2 stitches, work 5 dc in the next stitch (this is the sc from the previous row), skip the next 2 stitches, sc in the next stitch (this is the center dc of the shell from the previous row). Repeat from * across the row, ending with a sc in the last stitch. Turn.

This row is essentially a repeat of Row 2, but it's now perfectly offset to build the wave pattern.

Rows 5–80: The Main Body

Rows 5–80: Repeat Rows 3 and 4 alternately. This means you will work Row 3, then Row 4, then Row 3, and so on. Continue this pattern until you have completed 80 rows total.

Color Changes: To achieve the beautiful striped effect, change colors every 10 rows. For example:

• Rows 1–10: Color A (Seafoam)
• Rows 11–20: Color B (Sand)
• Rows 21–30: Color A
• Rows 31–40: Color B
• Continue alternating every 10 rows until Row 80.

How to Change Colors: When you are ready to change colors, work the last stitch of the row until you have two loops left on your hook. Yarn over with the new color and pull through both loops to complete the stitch. This creates a seamless color change. Do not cut the old yarn; simply carry it up the side of the work, or cut and weave in the ends later for a cleaner edge.

Finishing & Border

Once you have completed Row 80, fasten off your yarn. Now it's time to add a beautiful, polished border.

Round 1: Attach your yarn in any corner. Work a round of single crochet (sc) evenly around the entire blanket. When you reach a corner, work 3 sc in the corner stitch to ensure the corner lies flat and doesn't curl. Continue around the entire perimeter.

Round 2: For a neat, professional finish, work one round of reverse single crochet (also known as the crab stitch). This is worked from left to right (or right to left if you are left-handed), creating a twisted, rope-like edging that beautifully frames the blanket.

How to Work Reverse SC: Instead of inserting your hook into the next stitch to the the left, insert it into the stitch to the right. Yarn over, pull up a loop, yarn over, and pull through both loops on the hook. Repeat this in each stitch around the blanket.

Finishing: Fasten off and weave in all loose ends with your yarn needle. Blocking the blanket (gently wetting it and laying it flat to dry) will help even out the stitches and enhance the drape of the fabric.
