Recycled Bottle Cap Photo Magnets Tutorial Part 2.
You can see the first part of this tutorial here.
Glue the magnets onto the back. This is the final step, but I had to wait to put it up here because I was waiting for the epoxy to dry. The epoxy takes about 24 hours to dry but I usually give it 36 just in case. I use very strong 1/4″ rare-earth magnets. You can by them at any crafting store and some people like BabeMagnet sell them on etsy. I use E6000 crafting glue to stick them on. This glue takes another 24 hours to dry but it sticks!
