Like Cole said it's not going to make the nicest coat unless you get a really nice northern bear with good hair and you are probably going to need a couple of them depending on what kind of coat you are looking for. Go to USA foxx & fur. That would be a place to start with a garment project. Not really anything to do with a taxidermist beside fleshing and drying the hide if you don't know how.
