My Potting Shed doors were salvage finds for $12 each~ you can see the before version with the tape on the broken glass.
Instead of replacing the glass in my back door, I decided to add a board and paint it with chalkboard paint.
I wanted to keep the door chippy and peeling, so I cleaned the door and removed only the loose paint chips. I watered down some green acrylic craft paint for a light wash of color over the existing white paint, then dry brushed some brown acrylic paint on to highlight some areas.
My board was a scrap left from construction, so the texture is rough, a board with a smoother surface is better suited for a chalkboard. I found chalkboard paint at Lowe’s, and painted a several coats. After it was dry, I seasoned the board with chalk~ you can see the chalk caught in the rough surface texture of the board.
