What material guitar strap would work for tie dyeing? I'm thinking nylon wouldn't be good, but cotton might work. I'm resurrecting an Aria Pro II RS 600 and since it's kind of a Jerry Garcia sort of guitar, a tie dye strap would be appropriate. I've got a local guy to do the dyeing, but I need to provide a strap. He suggested a rayon material, but I don't think I've ever seen a rayon guitar strap.
