Moire
Moire is a waved or watered effect produced especially on grosgrain silk and woolen moreen via engraved rollers and high pressure on carded material. The end result is a peculiar luster which works best when made from a corded fabric like grosgrain.
During the Middle Ages moire was held in high esteem and was, as currently, used for women’s dresses, capes, and for facings, trimmings, etc.
