Supplies: 1/2 cup acrylic paint (choose any color you like, or mix colors together to make the perfect shade!), 1 tablespoon unsanded grout (this can be purchased at most hardware/home improvement stores, we got ours at Home Depot), mixing cup or bowl, spoon, paint brush and an object or board you plan to paint on.
Once your chalkboard has fully dried be sure to slate the surface before using it for the first time. To slate a chalkboard lightly rub chalk along the surface and then lightly rub it off.
Very cool. I suppose paint might stretch the definition of a gadget but one of the nice things about having your own blog is you get to decide what fits. This is a pretty cool idea so I included it.
