Dabu is a style of printing in which a paste made from calcium hydroxide (black clay), pounded wheat, gum, lime and water is printed onto the fabric. It is then covered with saw dust to prevent the design sticking to itself, and excess saw dust is removed. Once the mud is dry, the fabric is dipped in an indigo vat over, and over until the desired shade of blue is achieved. The fabric is laid in the sun to dry, and then the mud is washed off the fabric, revealing the design beneath.
