Kasuri is the Japanese term for what is commonly knows as ikat weaving. The kasuri process involves yarns being tied before they are dyed. The areas where yarns are tied are "masked" and will resist dye. The way in which yarns are tied will determine the look of the finished patterns which will be woven into the cloth. Sometimes just the weft yarns are tied. Sometimes both the weft and warp yarns are tied, and this is called double kasuri--a technique which can yield designs that range from simplistic to marvelously complex and pictorial.
