From Paleolithic times onwards, people have made and used skin rugs and cloaks out of necessity for warmth during the colder seasons and to lay on at night to sleep. We don't "need" fur rugs today, and not everyone appreciates them, but unmistakably, they do add to the rustic decor.
As a youngster I remember going to my uncle's cottage where they had a large bear skin rug on the floor in front of the fireplace. I was fascinated by it.
Fast forward to 2003 when we bought our lodge. The first time we viewed it there were two bear skins on the the living room wall. A small brown bear and a larger white bear. When we went back to look at the place again a few weeks later, the white bear was gone so when we drew up our offer to purchase, I put the bear on the wall into the offer. The bear is still there.
The price of a real bear skin rug can range from a few hundred dollars to $1700 and more! Also note that black bears aren't always really black, many are actually chocolate, brown, cinnamon, and blond. Blond is the most rare and therefore more expensive.
Artificial animal skins and furs are also available and they are generally less expensive than real furs.
Here's a selection of animal skin rugs, real and artificial, you can browse (we haven't found a source of bear skins yet---but we're looking).
