Love this idea from Martha Kids for recycling smaller bits of crayon into custom-shaped oversize crayons. A glass jar of these custom crayons would be so pretty on a shelf in the art room.
EDIT: Looking for heart shaped bake ware? Try these silicone ones from Target. Or this one from Wilton (it’s deep, so I would only partially fill it for this project.) Has anyone seen a heart baking tin like the one pictured above? My came with Maude’s Easy Bake Oven.
