I made it for a single bed, with plenty of overhang - it's shown here spread out on my double bed, so it's definitely plenty big enough! I plan to update this post in the next couple of days with some close up images of the individual squares (quite possibly in various stages of completion!), but I don't have them on the computer right now.
I took the basic idea for this blanket from knotyournanascrochet.com, but designed all the appliqués myself (which possibly explains why the bottom 'rainbow' fairy looks particularly psycho!).
More updates soon!
