After designing and using one of my coupon clutches, I came to the conclusion that the closure MUST be changed. Originally, the clutch was held shut by a button/elastic closure that (upon using one for a few months) never stayed closed to my liking. So I put the one clutch I have left on clearance and proceeded to make more coupon clutches using my old standby closure: Velcro! I am much happier with this. It stays SHUT!
