If you're looking for a cool project you and your children can create this Valentine's Day, crayon hearts are one super-easy idea. Just pick up a cookie sheet with heart-shaped molds and gather up all the wax crayon stubs you can find. Take off the wrappers and stick the crayons in each little heart. No need to worry about the color combinations -- the more mixed up the colors the merrier. Melt the crayons in the oven, let them cool and the coloring can commence.
There are lots more crafts perfect for Valentine's Day you can try with your children, too. Tissue paper flower bouquets, heart-shaped pins made of plaster of Paris and spinning paper mobiles of Xs and Os are all creative ways to share the spirit of the holiday with children.
