The right kind of fur is always a pain in the apple to find, and sadly sometimes you do just have to settle for a substitute. I usually prefer Mongolian sheepskin, but it's hardly commercially available, so I find myself sometimes having to go with luxury shag instead because it comes in the same colors, but the fabric itself is so thick and heavyweight (and the pile isn't as good either) that it makes for some stiff and cumbersome puppets.
