Crochet Stitches & Techniques
Double Crochet (dc)
- Yarn over & insert hook in next stitch.
- Yarn over and pull up a loop. You will have 3 loops on your hook.
- Yarn over and pull through 2 loops. You will have 2 loops on your hook.
- Yarn over and pull through remaining 2 loops on your hook.
Single Crochet (sc)

Half Double Crochet (hdc)

- 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.
Increases are made at the end of each row. To make an increase you will chain 6, dc in the 4th 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.
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 1: Crochet Sea Animals Blanket
Firstly, crochet each sea animal pattern. Click on the title or image below to go to that pattern.
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.
Step 3: Crochet Sea Animals Blanket
Now it’s time to add a border.
I made a Scallop Trim border.
