Chalk Board Table from Joan Eppehimer on Vimeo.
The surface is quite gritty, but I read you can sand it with 150 grit sandpaper. Since I already primed the table you see in this, I can't sand it...BUT I can try the one that is under the blue tablecloth.
In our case, this project was kind of a dud. The kids enjoyed painting the tables, but so far, no one enjoys coloring on them as a pre-class activity. I will have to think of some creative ways to incorporate these into class. The surface does not look as nice and black as I thought it would either. A little disappointing.
