Generally regarded as the best method for indigo dyeing of yarns. These yarns are twisted together until they form a rope and then briefly dipped in indigo baths.
Because of the short dyeing time, the dye does not fully color the yarns. The resulting ring-dye yarn therefore fades faster than yarn that has fully absorbed the indigo. One of the three main methods to dye indigo yarn, also see ‘Slasher Dyeing’ and ‘Loop Dyeing’.
