Softening Pelts and Hides

It's an unseasonably warm day in Maryland today. So I took out a few pelts I need to finish and a deer hide I didn't complete last summer. I have one raccoon pelt and two gopher pelts from the Bitterroot Valley in Montana. The raccoon is from last summer in Virginia.
The hide is a Whitetail Deer Hide I acquired from a friend who is an expert braintanner.

The raccoon pelt is on the left an has been frozen since last summer, looking more like a bundle of fur or a big owl pellet. The gopher pelts have been salted and stored in my garage, and appear to be fine. They just need to be scraped, maybe washed and softened.

The hide is pliable, but not soft and open as you would expect with buckskin. I think a good working over a post or cable should soften it up enough to be of use. I have a particular project in mind, so that's the driving factor behind finishing these pelts and hide.

I will probably use a 2x4 either lashed to two trees or with a beveled edge to soften these.
