Stage curtains are large pieces of fabric that give a theatrical performance its appearance when pulled back to reveal the stage. Typically these curtains serve different purposes, and they can be divided into front curtains, drapes that hang off the back of the stage (usually referred to as trimming), cross-stage curtains (curtains hung in front of the main curtain on either side) that help to shape and change the appearance of the stage while also giving some dimensions to spaces on either side.
