Leather

Is there any animal (other than, say, bugs and other things that don't have skin) whose skin can't be made into leather or otherwise cured in some way? If so, why? Chemical composition? Size/thickness of the skin?

Also, can you cure the membranes on bats' wings? I'm asking more to get perspective on the potential of dragon-wing cloth than anything, but I'm also curious about the answer for its own sake.
