A revolutionary new watercolor surface made of 100% cotton. The unique texture of an all natural woven material, in combination with a proprietary patented, specially formulated acid free coating, delivers a unique new watercolor painting experience and distinctive look that can only be captured on real canvas. Watercolor Archival Boards and Stretched Canvas are designed not to buckle. Unlike paper, Watercolor Canvas is more durable. Watercolor Canvas will not tear like watercolor paper can, so you can scratch it, scrape it, staple it, wet it and re-wet it and it will not damage your canvas.
