This is Mediterranean Mermaid. She's actually pretty small. I was very surprised when I went to cut the fabric because I always had this idea in my head that all Mirabilia mermaids are huge, but she's only about the size of the Nora Corbett flower fairies.

Looking at the chart her tail and fin are almost entirely Kreinik and beads. She's stitching up so fast (especially after Cindy's Dress) that I'm tempted to keep on working on her.
