also do you repurpose old pins/badges or start with new materials?
Well, I live near a button store (yes! a BUTTON STORE!) and they have fabric-covered button blanks in every shape and size imaginable, so I've been using those, and they work so well. I've been using repurposed and scrap fabric that I have lying around, because you only need such a teeny piece for each one. One challenge is that I can't seem to find a teeny embroidery hoop anywhere, which would make it easier to use smaller pieces of fabric scraps. I know they exist, I've seen them before somewhere...
