Canvas is an extremely durable plain-woven fabric used for making sails, tents, marquees, backpacks, and other items for which sturdiness is required. It is also popularly used by artists as a painting surface, typically stretched across a wooden frame.
The liner is fixed inside the frame and appears between the image and the outer frame. Generally made out of wood or some other hard material, the liner may have fabric glued down to it. Liners are to canvases what a mat/mount is to a print on paper. [Artwork framing] Polystyrene or wood liner. Fabric-covered liner.
