I first discovered button hole elastic in clothes purchased for my kids. This ingenious addition to the inside waist of pants helps harried parents tighten the waist band of their offspring’s pants without resorting to a belt, which is particularly important during the bathroom independence revolution. I purchased some for my stash, and have used it to adjust clothing, for mask elastic (during the cloth mask years), and now to hold together a rolled mat. Sewing a button on both ends of the elastic allows an adjustable way to secure the roll, and the elastic between acts as a carrying handle.

I would put forth that button elastic deserves a place in any crafter’s stash, along with hot glue and duct tape.
