what is muslin used for
Muslin can be used to filter wine of impurities during the decanting process. A funnel with fabric stretched over the narrow end may be used to transfer wine or port into a decanter, keeping any sediment out. Due to its versatility, muslin is used widely in the theater.
In addition to the stage, muslin is useful in television and film. When painted in a uniform color, the fabric can be used as an inexpensive greenscreen. It may be bought pre-colored for this purpose, but it is also relatively easy to make with diluted latex paint.
The word muslin may not always refer to the cotton fabric described above. In Britain, any gauzy cotton fabric may go by the name, while in the United States, it may be used for any firm, sturdy, inexpensive cloth. In nautical slang, a ship's sails are referred to as muslin.
