Crochet Stitches & Techniques

Double Crochet (dc)

1. Yarn over & insert hook in next stitch.
2. Yarn over and pull up a loop. You will have 3 loops on your hook.
3. Yarn over and pull through 2 loops. You will have 2 loops on your hook.
4. Yarn over and pull through remaining 2 loops on your hook.

Single Crochet (sc)

1. Insert hook in next stitch.
2. Yarn over and pull up a loop. You will have 2 loops on your hook.
3. Yarn over and pull through both loops.

Half Double Crochet (hdc)

1. Firstly, yarn over & insert hook in next stitch.
2. Then, yarn over and pull up a loop. You will have 3 loops on your hook.
3. Lastly, yarn over and pull through all 3 loops on your hook.

Corner to Corner (C2C)

Corner to corner (C2C) crochet is a technique where you crochet “squares” in diagonal rows. You start start in the bottom right and end in the opposite top left corner. Each row is increased by one square. Each square in the graph = chain 3 + 3 double crochet.

C2C Increase

Increases are made at the end of each row. To make an increase you will chain 6, dc in the 4^th chain from your hook and dc in each of the 2 remaining chains.

You will have a chain 3 + 3 dc square. This is your first square for the beginning of the next row. Turn your work and join with a slip stitch to the chain 3 space from the last square made.

C2C Decrease

The first decreases for both the width and length will create corners.

To make a decrease, when you reach the end of the row, you will turn your work and slip stitch across the 3 dc’s in the last square made. Join with a slip stitch to the chain 3 space and chain 3 + 3 dc.

Step 2: Crochet Sea Animals Blanket

After you crochet each C2C sea animal, decide how you to arrange them.  I decided to make my sea animals blanket two squares wide and three squares long.

Make sure all of your sea animals are facing the right way!

Line up the single crochet stitches from the borders. You can use locking stitch markers to keep them lined up.

Sew the two squares in each row together, then sew the three rows together.

Weave in all of your loose ends.

Now it’s time to add a border.

I made a Scallop Trim border.

Switch to Minty yarn
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.
