Crochet Blanket Pattern Finished Measurements

My crocheted blanket measures 45 inches by 67 inches.

4 squares (ch 3 + 3 dc) = 2 inches

Crochet Terms

c2c Crochet Technique

The sea creatures are made using the c2c technique of making “squares” back and forth in diagonal rows starting in the bottom right corner and ending in the top left corner.
Each square is made of a chain 3 + 3 double crochet.
Chain 6 to start a new row and chain 3 to start a new square.
You can follow the picture graphs or the written patterns.
The written pattern tells you how many squares to make of each color and in what order.

Assembling your Crochet Blanket Pattern

Sew your crochet sea creature squares together. Make sure they are facing the correct way. You can use locking stitch markers to hold the squares together.

Crochet Blanket Pattern Border

Start with blue yarn. Switch to minty yarn for round 2.

Rnd 1: Ch 2, hdc in each stitch along the crochet blanket edges. In each corner make (hdc, ch-2, hdc), join.

Rnd 2: Ch 2, *skip a st, 4 dc in next st, skip a st, slip st in next st* (repeat between the * all the way around), join, fasten off and weave in ends.

Finishing your Crochet Blanket Pattern

Weave in your ends. Block if desired.
