FAQ
Why is cotton fabric washed before tie-and-dye and why is a fixer (mordant) added?
Pre-washing removes starch, oil and dirt so the fabric absorbs dye evenly; adding a fixer or mordant (such as salt, alum, vinegar or baking soda) helps bind the dye molecules permanently to the cotton fibres so the colour does not wash out.
What are some famous traditional tie-and-dye styles of India?
Bandhani (dot-tied patterns from Gujarat and Rajasthan) and Leheriya (wave-striped patterns from Rajasthan) are famous Indian resist-dyeing traditions.
