Well, I softened it today and it was easier than anticipated. This may have something to do with the fact that the hide has been in the solution for a few days waiting for a sunny day, and I'm sure the vinigar helped to. It was amazing to see a slippery animal skin turn into leather just like that. I thought it was turning out softer than it did, but it is about the consistency I was looking for. I left a little grain on the back, but that is coming off with a little abrasion. It's airing out now, I will post photos later today.
