I doubt seriously if he is talking about having the same taxidermist cape it,that is going to mount it.
I don't charge for caping deer I mount either but I do charge $50 to cape,split turn and salt capes to take home.
That brings up another point.Are you talking about learning to skin off the cape or do the complete fleshing,turning of ears,splitting of lips,eyelids,nostrils and lips ?
If you are going to do all that,ie get it completely ready for salting,you need to work for someone and learn to do it properly or at least get a video and go through several practice capes before working on one you want to keep.
Caping a deer and doing the complete caping and fleshing,are two entirely different things and one requires a lot more skill.If you are doing the whole 9 yards,you may wish you paid $50.
