Early yesterday morning as I was traveling down the highway I noticed an otter dead on the side of the road. I drove on past but started to think about how beautiful their fur was, so about three quarters of a mile I turned around and picked it up. It must have been freshly killed and I soon skinned it. It was a large male and was very fat. I would like to tan the skin with the fur on it and use it in "Indian costume" for knap-ins. Is brain tanning like for a deer skin but with the hair on the best option? A little advise would be great.
