Halloween party invitations are spooky and fun when they seem to glow in the dark.

Print invitation text on computer postcard paper (8 1/2-by-11-inch sheets perforated into four sections). Use painter's or masking tape to secure the cards, information side down, to the work surface. Evenly tape the entire border of each card. Color the backs of the cards completely with brightly colored crayons, then coat with a thick layer of black tempera paint. Once the paint has dried, ask your favorite young artist to etch designs on the black background. To vary patterns and line thicknesses, experiment with such implements as plastic utensils, nails, toothpicks, and coffee stirrers. If you end up with extras, frame them with orange construction paper and use them as decorations at your party.
