We have been buying brains at the super market. They will order cases of pig brains for us. $30 will get you a case and enough brains for about 12 deer hides. If not we use ivory soap and veg oil. I guess this isn't "easy" but its simple. The more hides I've done the quicker I've gotten. If I have a block of time to work on deer hides I will use a wet scrape technique. It takes me about 30 minutes to flesh a hide, I throw it in a buck solution for 3 days, another hour( on a hide that cooperates, can be many on one that doesn't) to grain it, throw it in the creek overnight to rinse, a few minutes to brain it and I can frame soften it over a fire(be careful to not burn it) in about an hour. If I don't have a block of time, I flesh it and put it in the frame to dry scrape. If I get a minute here and there I can go to the basement to dry scrape it. I just brain it in the frame and soften when ready. Lots of times I'll work a few hides up to the braining step and freeze them. Then a can finish a bunch at the same time. Sometimes I soften inside while watching tv, other times out by the fire in the yard. We often have tanning parties, a bunch of us get together, fire up the grill, crack some beers and work hides.
