I like to give my kids a Valentine that isn't candy and won't be thrown away at the end of the day so I make them each a heart shaped crayon. It's really easy to do and it recycles our old and broken crayons.
Simple remove the crayon wrappers, break into small pieces and then melt the crayons in the oven just until liquid. You will need to use a silicone baking tray for this project. Once the crayons are cooled, then you can pop them out of the baking tray.
I let the kids choose their own crayon Valentine. I like to make them with lots of different colors, but you could make them with just one or two colors if you prefer.
Happy Valentine's Day!
Have fun making these!
