Mermaid Blanket Crochet Pattern

This week on the blog there has been a Fishing Net Blanket, Mermaid Baby so lets keep that theme going with now a Mermaid Blanket. The Mermaid Blanket is designed for older children (about 3-12 years). This blanket is fun to make and bulky projects are quick projects too. Do you know of a little girl who would love to be a mermaid and can do that while being comfortable snuggled up reading a book or watching tv. The Mermaid Blanket uses basic crochet stitches to make this design.
