By Judy Morris. In this art instruction video workshop you will see precisely how to choose the right colors and salts and how to increase your watercolor versatility with the subtle differences achieved by combining opaques, transparents, and stains. Get a close-up view as Judy breaks a few "rules" as she applies salt, changes in color, 'tweaks' it after it dries and finishes with an opaque glazing to make an everyday wall into an inviting subject for any watercolorist.
