I love the summertime, the sun, and swimming. I’ll never forget my first snorkeling experience, where I was able to swim with the fish and look at all of the beautiful, colorful life in the sea.

Unfortunately, I don’t get to see much of the ocean life unless I visit the aquarium. Thankfully, there are patterns for crochet sea creatures available so that I can bring elements of the sea home to me!

3. Blobfish Free Crochet Sea Creatures Pattern by Spin A Yarn Crochet

This blobfish will definitely convince you that this sea creature can look cute! You will be using the shape of an open round of stitches as the main design feature — the mouth!

The bottom of the blobfish is concave, making it the perfect little desk companion — it sits perfectly flat!
