Being an active drummer I end up with piles of "used" drum heads. The modern drum heads rarely break or tear if tuned and treated properly. I dont play like a gorilla either, so they saty put until I cant keep them tuned to my liking. Then I repalce them. Here is my idea. I use clear, single ply heads. I am going to back a bow with some of them and see what happens. The heads are designed to stretch like crazy without breaking. I see no good reason a guy couldnt hold some splinters down and still be able to see your bows true color, stained or not. Call me crazy.........the clarified calf skin thing triggered this idea by the way.
