Shot silk

Shot silk (also called changeant, changeable silk and changeable taffeta) is a fabric which is made up of silk woven from warp and weft yarns of two or more colours producing an iridescent appearance. A "shot" is a single throw of the bobbin that carries the weft thread through the warp, and shot silk colours can be described as "[warp colour] shot with [weft colour]." The weaving technique can also be applied to other fibres such as cotton, linen, and synthetics.
