I enjoy the look of white chalk (sometimes with a hint of colour) on a black chalkboard. When I was little my favourite thing was drawing a special image on the classroom blackboard and writing P.L.O. (Please Leave On) for the janitor to leave the image there for my class to enjoy the following day. I guess the nostalgia lives on as I’ve used this medium in a number of the parties we’ve thrown and now I even created a blackboard wall at my workplace as well!
