Aunty Biscuit has been asked by a friend if she can come up with a pattern for a mermaids tail for granddaughters dolly.. I think she will need help from Mum on this especially on the tail shaping.  As she has an ideal yarn in mind for it which is double knit weight I suppose the question is whether to start at the waist and knit down or the tail and knit up.  I will keep you posted on the outcome of such discussions.  I would suggest that this will put anything mushroom related temporarily on hold.
