Taxidermists will sometimes have an extra cape they'll sell you. If not they can order one for you. My dad had a big whitetail mounted and ordered up a cape for 70 bucks. If we're lucky I'll get a mulie with my bow and you can have my cape. Unless its an absolute monster and the wife will let me mount another one.

Good luck
