My son has a fascination with the moon so this would be perfect picture this. a bedroom wall, painted in blue-black chalkboard paint, chalk drawing of the moon, and finished with a curtain of white holiday string lights.
I love the idea of chalk paint in bath/powder room that guest use. or a wall paper or paint that would be easy to graffiti. then leave a cup of chalk or sharpies on the counter so every one can write on the wall.like a public restroom
