Organza fabric is a thin, plain weave, sheer fabric traditionally made from silk. Many modern organzas are woven with synthetic filament fibers such as polyester or nylon. Silk organza is woven by a number of mills along the Yangtze River and in the province of Zhejiang in China. A coarser silk organza is woven in the Bangalore area of India. Deluxe silk organzas are woven in France and Italy.
