What ''is'' the difference between draperies and curtains? Both are window length, unlined and serve fashion more than function. Draperies, on the other hand, are floor length, lined, fuller than curtains and often times have a pull cord to draw them back. Choosing one over the other depends on the size of the window you are covering and the look you are going for.
Fabric
Both draperies and curtains come in a wide variety of fabrics. For a more casual look choose brocade help keep a room dark. Many of these fabrics offer textured versions which will give your window more dimension.
