I read in the pattern notes of several other crocheters on Ravelry that this patten runs big. Although I did work it in a yarn larger than that suggested by the pattern, and I went down a hook size to compensate it was still big on me; and I have very broad shoulders (so much so that I often have trouble finding a tailored shirt that works for me). So choose your gauge accordingly. I might even suggest crocheting in the round so you can try it on before the whole thing is completed and it falls off your shoulders.
I think this wrap it just the sort of thing you might need on a chilly night at the Magic Kingdom. Not too much, but just enough to warm you up. And it could be themed for several of the Disney princesses, depending on the one you like best. In fact, you should check out this beautiful wrap that TicTacTo whipped up. It reminds me of Tangled!
If you crochet this wrap I'd love to see it! Until next time, may all your days be filled with fairy dust!
