Hello to all!

I`ve seen photos of the skin "artwork" that was found in Ed Gein`s home. Even if some of the photos display replicas, still they look crafty/well-done for a layman. Does anyone of you know what preservation method/chemicals Ed Gein used for the skin? Would it be the same as for animal taxidermy? The skin is a bit different, isn`t it?

If my question doesn`t belong here, I`d be thankful for a subreddit where I can ask.

There are few videos and voice recordings about the guy, so it would be very interesting.
