Tales of Mermaid Tails

How many of you have seen the latest trend for mermaid tails to curl up and watch TV in.  I am making one for a friend's daughter -- freely adapting the pattern below by Angie Hartley.  My version is in Drops Andes with an acrylic glitter yarn woven through to make the scales effect (picture of part of it in denim blue).  I'm finishing off the fin now which I'm doing in the glitter yarn.   I then need to finish a waistcoat in West Yorkshire Spinners DK and make a cardigan for my sister in Drops Belle.  Can Christmas be delayed slightly please ... !
