Velvet damask is a type of fabric that is characterized by a smooth and soft pile on one side, with a contrasting design that is created using a woven pattern on the reverse. The design is often made using a lustrous yarn, such as silk or a synthetic fiber, to create a subtle sheen. This type of fabric is typically used for high-end upholstery, curtains, and other decorative applications due to its rich, luxurious look and feel.
