It is a cosy blanket for my 4 (nearly 5) year old daughter to snuggle up in on the sofa. I had seen other mermaid tails on various sites but I wanted one which could be made with chunky yarn instead of holding 2 strands together. I also didn't want too many colour changes and ends to weave in, which is what a lot of the patterns I had looked at required. I found this Yarnspiration pattern which was quite simple. I substituted the yarn, choosing 'mermaidy' colours in a similar weight as suggested in the pattern, & I adapted the pattern slightly at the bottom of the tail.
