Chalkboard paint - Slate like finish
Empty frame - any size you should choose
Shower Board - cut to the size of your frame (you can find this at Home Depot, and they will actually cut it to your desired size)
Paint the chalkboard paint directly on to the shower board surface. Paint one full coat, then wait for it to dry before applying another. We used 3 full coats.
Insert fully dry shower board into frame and secure.
Write many notes. Enjoy!
