That was the first thing I did, size them up to see if I could use them as a bow backing. The first one had a messed up skin. He got injured some time in life, which messed up the skin. The second two were too short. Besides, ive got a few skins already tanned and waiting for bows. Ive got a few snakey staves I cut last winter that are just about ready to be made into selfbows. Ill be backing them with some skins ive gotten this year.
