I found these directions on how to make homemade stickers on my money saving ezine:  Have your child draw or stamp a design on paper. Combine 1 packet unflavored gelatin, 6 tablespoons warm water, half teaspoon vanilla or mint flavoring. Apply "glue" to back of paper with a paintbrush. Let dry. Cut out. Use stickers by licking the backs or wetting with a damp sponge.
