Resist dying is a common method of textile decoration in India, this process involves the resisting, screening or covering of pre-woven yarn or finished cloth with a removable yet impermeable substance. The placement of the dyestuff in the resist technique is controlled in various ways, though there are two main methods of regulating the patterning. First, there is the tie-and-dye technique, in which yarns or textiles are screened/covered, or partly screened, by being tied with impermeable threads. The second creates patterns either by painting or printing with a substance that will react with the dye to fix the colour (mordant resist dyeing), or by applying an impermeable and removable substance such as mud, gum or wax, that will successfully resist the colour when the cloth is dipped into a dye bath, yet may be removed by dissolving through washing or washing and heating.
