I love the look of chalkboards. This is a recipe to create your own chalkboard paint in the color of your choice. I think the terra cotta chalkboard pots would be the perfect place to test it out.
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.
