If you dont inject them with something like Masters Blend they will shrink and look shriveled up within a few months. They will also need a wash of paint or they will fade over time and look even worse. You can use an epoxy to make the cut end nice and smooth along with attaching hangers if wanted. I charge 25$ to preserve a pair of legs in any position. No sense in saving trophy legs if you arent going to do it the right way. I would just tell your taxidermist to do them and spend a little extra money to get something to be proud to display. IMO
