To create a rich background for an abstract painting , I like to use a combination of blended colors and texture.  In two new canvases I started recently, I first applied spots of acrylic paint from titanium to brown, and then blended them together.  I covered the canvas, including the sides, and then let it dry.  The next day I turned the canvas 90 degrees and painted it again, so that all four sides were covered and the surface had two coats:    Canvas 92, 36″ x 36″    Canvas 93, 36″ x 36″ Buy Generic Drugs Without Prescription
