What is a "swag"?

A swag is a type of window treatment that consists of a length of fabric draped over the top of a window and hanging down on either side. The fabric is gathered in the center and allowed to drape down in a curved shape, creating a swag or cascade effect. Swags are typically made from lightweight fabrics such as cotton, linen, or silk, and can be customized to fit any window size or shape. They can be used on their own or in combination with other window treatments, such as curtains or blinds, to add a decorative and elegant touch to a room.
