A short time ago I took a watercolor painting class. In this class we used watered down watercolor paints in spray bottles. As you spray the primary colors onto our watercolor paper the colors blend to create the completed rainbow effect. Once the backdrop dried I decided I could probably finish the picture by stamping elements found in my nature clear rubber stamps. The theme I was aiming for is stamped in mini alphabet letters for a completed project.
As you can see, there is no limit to the background possibilities that can be created using simple water colors and nature clear stamps.
