While I own a 1 inch button maker, my friend Joanna and I rented a slightly larger one for a weekend a while back and went crazy making larger magnets. I packaged mine into little zip locks, in sets of 2 or 4. Joanna had a great idea to create larger sets of her photography magnets and she packaged them in old CD cases.
They look great and it’s a great use of cases when you store your CDs in another way.
