The variety stretched cotton canvases are a versatile artistic medium. You can use them as canvases for watercolour painting, oil painting, acrylic painting and much more. Experiment different artistic styles and mediums on the surface of our blank canvases! Our stretched canvases are ready to paint. The prime joint structure is stapled in the back and includes wedges to adjust the frame. If the canvas gets loose after usage, you can easily adjust the wedges in the corners. This way you'll stretch the frame and your artwork will look as good as new!
