Wellllll.... what I was thinking was that I might like to try using stingray.... the tanned form is still very thin, but I wasn't sure about the overall advisability of using tanned skin. The rawhide form, referred to as "crust" could be used I suppose, but I don't know whether or not that sort of thing should be pieced together (a large crust is about 20-24 inches, bow is 68). There IS a variety called a rowstone that can be had in the 34+/- inches tanned, but I cannot find it in crust form.
