Duvetyne Cloth

What is duvetyne cloth used for? What is so special about it? Explain three different uses for it on set and what you should bring in addition to use it. 

Duvetyne cloth can be used to black out a window so that the lighting doesn't change according to the time of day. It can also be used to skirt lights in order to prevent unwanted light leaks. This kind of cloth is heavy enough to be unaffected by slight wind and does not cause much noise for the audio department. They are also the right thickness to efficiently block out the light without doubling them up like bed sheets. The fact that the cloth is flame retardant is key to keeping the set safe at all times.
