Follow these instructions for do-it-yourself skin heads. Lay a sheet of polyethelene (visqueen) plastic on the floor of your barn more than twice the size of the hide. Set out the skin, hair up. Cover completely with hardwood ashes, don't skimp. Dampen down the ashes with a sprinkling can of water, it'll become like a paste. Cover over with the rest of the plastic and fold the edges over to hold in the moisture and drop a sheet of plywood over the whole thing to keep out the dog. In three to five days (depending on the temperature) check it with a putty knife, the hair should slide right off, if not, set a while longer or reapply if you have a stubborn spot. Not too smelly, little fuss, and not too much of a mess. Have fun.
