I would not even consider de-hairing that hide. It is much more valuable as it is. Moscow Hide & Fur had a hair-on moose hide for sale a year or so ago, and I think they priced it at around $800. Big, fuzzy hides from large wild animals are not cheap. I understand that much of Europe is being overrun by wild boar, so raw skins should be plentiful, but Jelling Dragon has large tanned hair-on boar hides that still cost around $200. Moose are not so plentiful.
I was thinking of ordering one of those boar hides, but I'm sure if I did, the pelt and I would both be banished to the tool shed.
How long is the hair on that moose hide? I have never handled a hair-on moose hide, but if it was from an animal killed in the wintertime, I would guess the hair is both long and thick. It might look kind of funny on smaller projects unless the fur was shorn close.
I know cold-weather moccasins were often made of hide with the hair on. I saw a pair of side-seam moccasins once that were made of buffalo hide with the hair turned in. They looked really warm. You would need to work up an oversized pattern for moccasins, though. My brother made some sheepskin (shearling) moccasins for his girlfriend many years ago, but cut the pattern to a size that would have fit her shapely foot perfectly, if it had been bare leather. With the fur inside, she couldn't even get her feet halfway in.
In my mind's eye, I'm seeing an image of Robert Redford as Jeremiah Johnson, wearing a set of enormous, furry half-leggings or botas. I could swear such an image exists. A set of those made from moose hide might be a possible project.
Anyway, if that moose hide were mine, I believe I would leave it whole and spread it over the bed on cold nights. If the lady of the house were to object, I expect I would move it into the man cave and lay it over the chair where I sit at my desk. I have a sheepskin there now, and it makes my industrial-grade chair a lot more comfortable than the chair would be without it. If you attend rendezvous or living history events, bring it along and you'll be the envy of the camp. At the very least, you should be able to trade it for an equal amount of hairless leather.
By all means, let us know what you end up doing with it.
Best regards,
Notchy Bob
