Are you thinking of using a real WOLF hide? Or are you calling a coyote a " prairie wolf"????
The Wolf is is a protected species, and possession of any part of a wolf can land you in federal trouble. There are Wolf hides taken in Canada, Where its legal to trap, shoot, and possess body parts, that are sold here, but you want to keep your bill of sale, and receipt to prove origin of your " hat " to avoid expensive litigation.
