Separate the crayons according to color. Some crayons are made out of different ingredients that will not mix with another type of crayon, so make sure your crayons are of similar type. Put one color in a small cooking pot and heat, stirring constantly, until crayons are all melted together. Carefully pour the crayons into a candy mold. Spring or Easter themes are appropriate. When dry, let the child remove and color with them. These worked really well as stocking stuffers and will work well as Easter Basket stuffers too. You can find candy molds to match any holiday in most variety stores.
