fishnhunt...here' s what I do.
First, field dress the deer, but do not cut up through the sternum. Then when hanging, I make a cut all the way around the deers mid section(about where your filed dress ended). Then I cut the front legs completely off at the elbows(saw). Then skin the animal down towards the head carefully and slow. Push the stubbs of the front shoulders through the hide and continue skinning down as far as you can to the base of the skull. Cut the head off and then you have it. Do not try and skin out the face, let the taxidermist do it. The end result is there will be no cuts in the hide at all, and it will look like a short sleeve tshirt where you pulled his shoulders through. Also, there will be plenty of hide for whatever pose mount you decide on. I do it this way so there aren' t any unneccesary cuts that the taxidermist has to contend with. He can make incisions where he wants. I know the old school way said to cut up the back of the neck....don' t do it. That' s just another seam that has to be dealt with. I don' t know if it' s the absolute best way, but it seems to work great. Good luck on getting one you' ll have to have mounted!
