The term 'curtain rod covering' can be summarized by the 6-letter word 'PELMET'. A PELMET is a decorative board or box that is placed above a window and is used to hide the curtain rod and the curtains. It is usually made of wood, metal, or plastic and is often decorated with fabric or other materials. Pelmets are used to add a decorative touch to a room and can also help to reduce the amount of light entering the room.
