A curtain is a piece of material, usually cloth, that hangs across a window or opening to make a room or part of a room dark or private. Curtains can also be used to decorate a room, block out noise or drafts, or create a theatrical effect. Curtains come in different sizes, colors, patterns, and styles. Some common types of curtains are sheers, blackout, thermal, grommet, rod pocket, and tab top.
