Sheep heads. A tearing question

[cimba.livejournal.com]

How would you proceed if you had to make a realistic sheep head?

There are those friends of mine who are preparing this theatre piece, and they asked me about a sheep head (well, a couple). The heads should be weared by actors so it's a sort of full hat thing or something. Thing is, paper or sort of are not a way I suppose, because my poor skills would not make it really realistic.

Please help this desperate nonsense girl.
