Im not into the head collecting thing,unless im eating the animal too,but dont get too general with the eating part.I trap alot of animals that i dont eat.However if i see a use for them i will take them apart and use glands,fur,skulls,etc.Even if its easier and cheeper to buy the stuff.I think its because i grew up in the late 60s and had to make alot of our stuff.we didnt have any money so if you wanted it,you made it.
