Cheap alternative to enamel

I've made enamel pins before, and they are great, but they are about 3 to 5 dollars each depending on quantity and quality. But they have a 50 pin minimum so if you only need 10, the sticker mule acrylic pins are a cheap option. Its basically a sticker on the back of piece of die cut acrylic, and there is an adhesive pin on the back of that sticker. One of the pins fell on the floor, and when noticed and picked it up later, the adhesive pin backing had pulled the center of the sticker off, leaving a transparent whole in the center of my pin. But at $1 a pin, with a 10 pin minimum, you get what you pay for.
