I started the process of making a new rawhide bowstring using the skin of a road-killed groundhog that I had recovered last summer. It's been in my freezer since then, waiting for me to have time to mess with it. My first order of business was to thoroughly scrape any remaining flesh off the hide. Next, I wetted the hide and rubbed hardwood ashes into the hair side. I folded it hair side in and put it in a bucket with just enough water to cover it. The hair started slipping a little yesterday, so I figure it should be easy enough to pull or push it off this evening.
