Canvas TCIDD is a canvas that is made from a thin (thin wall of canvas) fiber that can be used to create a wall of canvas that is strong enough to hold large amounts of canvas. TCIDD can be used in several ways, such as as a protective wall or as a temporary wall since it is a thin wall fiber. The fiber is cut into 10 squares. Each square is an inch wide and is mounted on a piece of canvas that is two inches wide.
