I found and I'm sure your experienced enough to know that taking your time/looking around etc./staying involved with this hobby and hobbies like it that you will see and get good ideas of what to make from the bear hide or just leave it as it is as a display somewhere.Just make sure your measurements are correct of course before cutting it up.I usually like to make stuff that is practical and useful but that's just me.
Here's 1 idea....Years ago I made a pair of prime coon hide vests.Took 9 of them for each XL vest only using the 6" wide center cut from the backs.Gave 1 to my dad.He would wear it around in public along with the coon hat.At the cafe/at the grocery store etc./all over.....lol.I just wore mine at rendezvous's.
Again congrats on your job well done there.I used to have a pair of bear hides years ago but traded them away for some odd reason.Did'nt tan them either.I think I traded them for more teepee poles.....lol.Used to put them across as is on some willow rod back rests.Not very good backrests but they worked great back in the day.It's gratifying to get yourself in the situation your in now so take your time.
When cutting up self done brain tan hides for projects I go through the same dilemma of decision making.
