I have a button maker that makes buttons about 1" in diameter. I use it to make buttons out of materials generally not intended for the machine, like fabric and beads and such. The two above were made of extra linoleum prints I made into cards last year, and are some of the only buttons I've made as intended, with paper and a plastic cover. Here are some examples of the other kinds:
And for fun, below is the first button I ever made, before I even had a button maker. There was a booth at the Oregon Country Fair that let you make buttons. I used a contact print of the first sheet of B&W photos I'd ever taken. That girl in the middle is my best friend Zella.
I'll be making a lot more buttons in the next week in preparation to sell at the Holiday Art Fair. Wish me luck!
