If you have old flip flops you want to spice up, add jewels or beads.
If you are really crafty, you can sew the beads or jewels on the flip flops, but you are also able to hot-glue them. Hot-gluing will be an easier method but the beads are also more likely to fall off if you do that.
Don’t forget to keep you hands away from the hot glue gun. You don’t want to get burned.
