Yes, animal parts. Horns, bones, leather, claws, feathers, fur, etc.
I stumbled across hideandfur.com when kicking around some armoring ideas, they have a great selection of items for making barbarian or scavenger costuming. They aren't the best source for cowhide leather, they have it, but it's sold by the whole hide, but they do have good prices on furs and such. Plus, they have a link to another LARP on their links page, so they must be cool people.
