When ordering drapes you should consider how thick the pleats in the fabric should be (click here for more about pleating). This is called the fullness. A drape that is hanging in “zero fullness” is perfectly flat – no pleats whatsoever. A drape hanging in “100 percent fullness” is pleated so that it takes up exactly half as much width as it would if it were not pleated at all. Drapes may be hung with more or less fullness, as is appropriate. Stage drapes, especially grand drapes, are usually manufactured with sewn-in box pleated fullness, which means that the pleats are sewn in permanently. This makes the pleats nice and crisp and even but does not allow you to ever spread the drape out flat. Read below to learn more about pleating and fullness.
