I just saw them on the Woolly Hugs FB page, but I'm not sure if you're on FB so I thought I'd say it here. They are gorgeous, beautiful colour combinations too. 
I looked that butterfly square up on Ravelry and I hadn't seen that designer's work before, so now I've added a whole load of new squares to my squares favourites folder too. This is the pattern for the butterfly square in case anybody else is interested.
