Available in several sizes, these professional-quality 100% cotton canvases from Winsor & Newton have been carefully manufactured using only the finest grade cloth & heavy-duty pine for a superior, attractive, exhibition quality finish. Beautifully responsive to every brushstroke, their unique smooth surface has been double-primed with acid-free, highly pigmented gesso for balanced absorbency & stapled to the rear of the frame for expertly tailored, seamless corners. Rigorously tested for warp-resistance, their professionally constructed 2.1cm depth frames have been built using kiln-dried, heavy-duty solid pinewood & feature slots for the included Pro-Stretcher device, providing the perfect tension every time.
