I think I'll have to give it a try and see how it goes. The way I was thinking was the bark tea method and let it soak. The main thing I'm worried about is the hair being matted down, though it should fluff back up while breaking the leather if it doesn't slip after the soak. I'll try it with a opossum hide first and see how t goes. My normal tanning method that I get good soft hides with is: flesh and dry, during the thick parts of the hide down with a sanding disk on an angle grinder, degrease with acetone, rehydrate in a wet towel overnight, slather on some warm diluted egg yolks, and break it. On raccoon and opossum sized things, one oiling is usually all that's necessary. Over thanksgiving break after boiling my traps? I'll just leave the tea to throw some hides in.
