Wool would be an interesting one, being largely existent already (fabric and fur), and although it could be a seperate way of creating them, it wouldn't be the new addition we need to get this suggestion out of the "Simply an excuse to add a farm animal" category.

The main issue is finding a use for wool that couldn't be replaced by fabric or fur. If you can do that, you're probably in the clear (as long as it is reasonable).
