From the craft store pick out some matte finish paint in the colors of your choosing. Using a foam or tight, thin bristled brush paint the outside of the jar. Allow to dry completely (about an hour) and repeat for 3 to 4 layers depending on your liking. Allow to dry overnight. The next day, using a very fine sand paper, lightly sand the raised letters, raised areas on mouth, and any small spots you want to have the rubbed/vintage effect.
