I know you said to ignore this, but I'll answer it anyway in case someone has the same question. It's textured stretch velvet. It's not the straight up normal crushed velvet you can get, the texture is a bit different, but it's a very similar fabric.
I think it has a really wonderful affect for her hair and it's a really good choice. ^_^ I'm not sure what I'm going to use for my Chrysalis's hair yet. ;_;
