I hope I'm not too late in answering. ^^;
Have you thought of making a kigurumi? They're comfy and really nice to wear in the winter, plus fleece is great to use.
However, it takes a lot of fabric... ^^;
I have the gallery created on my account, but haven't gotten around to adding pictures yet. If you'd like, feel free to PM me and I can link you to some pictures of my cosplay. :3
