It's fun to dip sponges into paint and then print to make exciting impressions. They're simple for young hands to use, just put a sponge in a shallow puddle of paint, blot on a paper towel and press onto paper. Create terrific T-shirts when you use them with fabric paints. You can use them with white glue, too, then decorate the impressions with glitter. Try them with liquid watercolors and color diffusing paper for a unique craft project. Easy-to-clean synthetic sponges are approximately 1" thick and 3" tall. 36 sponges: 26 letters and numbers from 0 to 9.
