Sometimes I like to work on a large scale. My car can only hold stretched canvases up to a certain size. When I want to work larger than the car's storage space, I paint on unstretched canvas and use a dowel system from which I can suspend the canvas for painting and displaying. All I have to do is roll the canvas up into a relatively small, space-saving and lightweight piece which easily fits into a modest-sized vehicle. Transporting is a piece of cake then. I call these large paintings "Roll-Ups". Necessity has been the mother to many inventions.
