Painted the frames (front & back) and the canvas a solid grey/purplish color (that looks very blue in the photo). Let all three dry. Hauled the 3 out to the back porch (putting down a large sheet to catch the overspray). Using stencils, applied various patterns/colors to the canvas. I want these three to be related, not identifcal. So, using similar colors/patterns on each .. with varying placements.
