14.5 x 21.5 in a 18.75 x 26.5 white mat -- Watercolor, acrylic, pen/ink This technique requires that the artist use liquid starch as a resist to save whatever design areas must remain white. Next spatter acrylic paint in a random pattern, let the paint dry, then wash the paper in a sink to remove the starch. Enhance areas with watercolor paint and black and white ink to further enhance interesting abstract areas.
