How to crochet a kids Sleeping Bag & Pillow?

Making a child’s Seal Crochet Sleeping Bag and Pillow Pattern is easy with this free crochet pattern. As well as knowing your basic crochet stitches, you will need to know how to work into front/back posts and loops too.

You’ll need some basic sewing skills to attach all the seals facial features, fins, appliques, and buttons.

The crochet sleeping bag also comes with two ocean themed appliques, a star fish and a sea shell for extra cuteness!

To complete the seal sleeping bag and pillow crochet pattern you will need some chunky yarn, buttons, a 6mm crochet hook, and a 20″ square pillow. If you’d like to use the same dreamy wool yarn as I used, you can get the yarn pack here.
