First thing I ask myself is what do I want to do with things.In the past I used to go to many buckskinning rendezvous.With bow making sinew of course is an option for bows and sewing/wrapping.I saw many other ideas out there for different animal parts too.I've made a few deer leg bags from legs.Made rattle wind chimes out of the dew claws and deer toes before.That's not including things to do with the bones.I've used them for knife handles before.It's up to you and your ideas of use really.
Some pics of their usefullness.
Muzzle loader shooting pouch.
A different type pouch.
One on far left is deer leg bone handle
Some deer toes and dew claws and a couple of wind chimes I made long ago.
I find that the pronghorn horn is a lot like the toes of deer too.Knife handles can be made of them too along with other things.It's up to your imagination to make anything useful from these things.
