Chalkboard paint is easily purchased at any hardware store. But it's only available in black or green. This recipe allows you to create the paint in any color you please:
3 teaspoons acrylic paint (color of choice)
1 1/2 teaspoons glazing medium (water-based)
1/2 teaspoon powder tile grout
Mix all ingredients together, blending very well. Make only as much as you need, as it does not store well...
