We grabbed the crayon box and the kids pulled out crayons with Valentine colors. Next I pulled out the wax paper and pencil sharpener. We sharpened the crayons to create shavings. This was quite a process, but we got good piles of crayon shavings.
After we placed the shavings in between two layers of wax paper. Then we ironed the wax paper on a medium setting until the crayons were melted.
Then using a heart-shaped cookie cutter, we traced hearts and cut out the shapes. Then strung with thin ribbon. Hang the hearts against a window that gets good light. I love the stain-glass effect.
