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!
You can find these magnets in my etsy shop. They are my newest addition. Rather buggy, don't you think?
