IMO, if you're wanting soft hides, you're best to send them to a tannery. You can home tan the hides with lutan, krowtann, mckenzie tan etc, but as they dry, they get stiff as a board unless you hand break them and once you try that, you'll wish you sent them to a tannery. If on the otherhand, you don't mind if they dry hard, then go with the krowtann. it's about $26/ quart and will tan quite a few yote size critters with one qt. Simple to use, just rough flesh and put the hide in the water/salt/krowtann solution. turn the hide every day for 3 days and neutralize with baking soda after that. No ph checks necessary!
