I saw this idea on The Creative Crate and immediately went to a hardware store near my home to get some washers. Let me say, these become very addicting!
A few changes we made to the instructions were:
**we used Mod Podge to glue the paper onto the washers. Once they were dry we put a top coat of Mod Podge on the paper.
**we used Aleene's Paper Glaze (I got it at Michael's) instead of Diamond Glaze.
They turned out great! My girls absolutely love them and can't wait to make more!
