A start to finish thread on your process would be interesting K Snow.
Here's a brief summary.
Start with fleshing the hide, just like doing any fur. Don't have to do a perfect job, as you can go over the flesh side again during hair removal.
To remove the hair, I soak the hide in a potassium hydroxide (KOH) solution until the hair slips easily. Traditionally this was done with wood ash. When the hair slips easy, use the fleshing knife and push off the hair, and the first layer of skin, the grain. This is the layer that modern leather has, but brain tan doesnt.
Once all the hair and grain are off, I go over the flesh side again.
Then the hide gets rinsed. I put it in the creek for two days, this rinses out the KOH solution.
The hide is now rawhide. Often I stretch it in a frame and let it dry until the weather is warmer.
To dress the hide, start by dehydrating it, a day in the creek does the job. Then wring out thoroughly. You want the hide just damp, no real wet spots. Then into the dressing solution it goes. I'll dress the hide for 18 hours or so. I'll wring it out and resoak 3 times in that 18 hours. Then comes the real work, as described above, to soften the hide.
Once dry and soft, the hide is smoked over a smudge fir to color it, and so it stays soft if it gets wet.
There's a lot more detail in each step, much of it learned by feel. Its a physical process for sure, but very rewarding.
I haven't done any fur yet, but that's on my list to try.
