@Lyanda -You know, it would be really cool if they came out with a rig that had items made from users.
@To the OP- Also, as everyone else is saying, as amazing as this item is... it looks like it would fall under the hair/wig tag unless you can add something to make it look more like a furry hat.
Hmm... why not allow some of the user's hair/bangs to be seen? That way it gives a two tone effect and it will look more like the avi is wearing something on their head. On a side note: I would buy them all.
