Black Stretched Canvas or pre-stretched (or box) canvas which is the familiar name among the oil and acrylic painters. A sheet of canvas is stretched across a wooden frame, This enables the canvas to be stretched evenly around the frame just like a skin over a drum. Further, the canvas is primed to ensure optimum oil holding and durability. In addition, we also offer Canvas Blocks which are basically papers of 230gsm (or more) paper. These papers have canvas textures on it and are suitable for both acrylic and oil painting.
