Just a practice tail I made using some extra fabric I had from a plush doll I made. Fur isn't long enough for my tastes, but okay.
It's plush fleece, and the insides are (unfortunately) filled with stuffing. One of those foam tubes would've worked a lot better. Seriously, if you make a tail, avoid using regular old stuffing.
Sorry for the weird lighting, etc. My tripod was being a pain, which is why there are two shots of it being worn.
The orange on the top right is what the color is, to deal with weird flash issues.
