The mermaid tail crochet blanket is made like an oversized bag, and you can scale that idea down to create bags of various sizes. This small crochet pattern is for a treat bag. It's a perfect choice as a giveaway gift bag for a mermaid-themed birthday party!

This bag is worked from the bottom-up, beginning in short rows for the tail and then going into rounds to complete the rest of the bag. The ruffles at the top are created using the crocodile stitch.
