I used this years ago and even then it was super expensive for a quart of the stuff- but now you can do it yourself for a fraction of the price! And you're not limited to the old school green or black. Any color you can have mixed at Home Depot or any other store, you can transform into chalkboard paint. So, if you want to match that kids' room just perfect or have a space in your kitchen for grocery lists. now you can. Anywhere and anywhere, any color you choose- how great is that? Here's the recipe that Martha herself posted: http://www.marthastewart.com/271574/make-custom-color-chalkboard-paint

Custom Colors How-To
Start with flat-finish latex paint in any shade. For small areas, such as a door panel, mix 1 cup at a time.
1. Pour 1 cup of paint into a container. Add 2 tablespoons of unsanded tile grout. Mix with a paint stirrer, carefully breaking up clumps.
2. Apply paint with a roller or a sponge paintbrush to a primed or painted surface. Work in small sections, going over the same spot several times to ensure full, even coverage. Let dry.
3. Smooth area with 150-grit sandpaper, and wipe off dust.
4. To condition: Rub the side of a piece of chalk over entire surface. Wipe away residue with a barely damp sponge.
