These wax paper hearts are a cheap and fun decoration for Valentine's Day!
Pretty much you just layer thick paper, then wax paper, then crayon shavings, then wax paper, and then thick paper again. Fold all the edges in to seal the shavings in (I tried to skip this step and ruined my ironing board!). Press with your iron on medium heat, with no steam. Let cool, remove thick paper, and cut the wax paper into hearts!
This idea came from Martha, you can find her tutorial here.
