Chalkboard Table Numbers: 1. Buy a frame you like that has glass. You can paint the frame too. 2. Buy Chalkboard spray paint!! Here or at a hardware store. 3. Wipe down the glass before you spray so there is zero dust or dirt. 4. Three coats works well, letting each one dry a few minutes in-between. 5. The chalk paint will become a matte finish when it's completely dry. 6. That's it! Be creative with your new chalkboard!
