Fun and Easy to paint! This glass block looks pretty lit up with a string of mini lights inside. It makes a great night light! Try to use a CLEAR string of lights as opposed to a white string of mini lights. Use a Glass Block with hole drilled in back. (Pre-hole glass blocks are available at some building centers like Home Depot, ...or it can be drilled by someone who installs ceramic tiles.) Uses DecoArt Glass Stain. Be sure to see our other glass blocks!
