With a generous 1.5" profile, these small back-stapled canvases have all the benefits of traditional canvases in a more decorative size. Each canvas features cotton canvas primed with a titanium acrylic gesso primer that's acid free and archival quality, and the medium tooth surface is ideal for acrylic and oil paints. They're perfect for a creative series, dimensional projects or polyptych paintings.
