Decorative blackboards and wall organizers can cost big bucks at popular retailers, but you can make them for just a few dollars. We found a pair of $10 picture frames at a secondhand store, bought a can of chalkboard paint for less than $5 and got the chalk for another $2. This project takes little time to make and is easy enough to have the kids help.
Spray or brush a little primer onto the surface and let it dry. Then apply a coat of chalkboard paint. Let dry and add a second coat if needed. Follow manufacturer's instructions for drying times. If you are not changing the wording on your project, you may want to use black paint with white paint for lettering instead.
Carefully start adding your words with the chalk (or white paint with brush). Use a T-square if needed to help keep your lines straight.
Clean both sides of the glass and then place the chalkboard back into the frame. If you're going to be changing your message frequently, you may want to leave off the glass. Carefully readjust the frame's metal fastener pieces with a flathead screwdriver.
