RE: Question about mounts
Its really easy guys...when in doubt, dont cut! Saw the legs off long, pull the skin over the resulting "stub" the same way you roll the skin down the body and neck. Its called tubing. Some of the newer style forms for mounts use more foreleg then youd think.
As for freezing, if its just going to be a couple days, keep it cool with a bag of ice, or fridge. I dont like taking in frozen deer heads at my studio, I cant see what condition theyre in until they thaw. My advice to you would be to choose a taxidermist, and then ask HIM what HE would suggest.
Lastly, when you visit him, he can show you examples of all those poses available, or go to McKenzie Sports Products online and youll see pics. Hope this all helps.
