Whatever the shape of your canvas, it’s important that your stretcher frame is constructed of quality material, and that it’s keyable so you can adjust the tension of your canvas over time. Some shapes make a keyable frame impossible, in which case the engineering and construction of the strainer is even more important. You can get canvas in the shape of an oval, circle, triangle, heart, irregular shape or even multi-layered with cut-outs. Explore the possibilities for your shaped canvas support here.
