First, clean the vases with hot, soapy water. Second, When they are completely dry, pour some surface conditioner in and cover the inside of the vase. Pour out the excess and let the vase dry. Third, Get the exact color you envision by mixing your PermEnamel paints in a mixing bowl, then pour inside the vase. Fourth, Paint the inside of the glass using the paint brush to cover the inside surface. Fifth, Once the vase is painted, lay it on a paper towel to let the thick paint drip off. You will be amazed at how much comes out. The longer it's upside down, the thinner the coating will be. If you like the thicker look keep it upside down only for a few minutes. Sixth, Turn the vase back over and touch up the drips inside. Every fifteen minutes you can even out the thickness on the bottom of the vase as the paint will start to collect. Seventh, Let these dry over night and in the morning you should have a beautiful decor vase! REMEMBER, never drink or put water in these vases!
