rubber apparel buttons from bike tires?
I made the bike tread belt, and of course wound up with two extra strips of rubber.
Then I cut out shapes from them, which I think could be used as apparel buttons (as opposed to on/off buttons.)
Is there an easier way to do this than with scissors?
Also, buttons are often harder than rubber tires, but I also know that rubber gets hard over the years. Is there a simple way for me to make the rubber harder?
