Native Americans made it a point to use every part of an animal they harvested. Today many hunters try to do the same by using feathers and fur for fishing flies and decoration. Rotting and mould are the biggest problems you face before use. Applying Borax is an economical solution to cure the hide or skin for storage or a wall mount.
Remove any meat and fat from the skin.
Nail the skin to a piece of plywood or similar surface. The skin side should be facing up.
Apply a 1/4-inch layer of Borax to the skin.
Work the Borax into the skin and let it sit for two days.
Remove any clumps of Borax every other day and add more to keep a 1/4-inch layer of Borax on the skin. Reapply for two weeks.
A window fan blowing over the top of the Borax will speed the drying process. The fan should be on the lowest setting to avoid blowing the powder off the skin.
If the skin gets wet after curing with Borax, the process will have to be repeated or mould and rot will set in.
