The technique has been built entirely around natural dyes and painstaking resist-printing. Cloth is treated, washed and printed in layers using hand-carved wooden blocks, with each color requiring its own printing and dyeing cycle – indigo for the blue, madder root for the red, and iron or lime-based resists to keep the white geometry crisp. A single length of fabric can pass through more than a dozen stages of washing, printing, and sun-drying before it is completely finished, which is why authentic Ajrakh work takes days, not hours, and why the deep reds and blues never quite look flat or synthetic.
