Stiching cloth: Tye-dyeing in China predates hippies 1000 years. While the Miao minorities in GuiZhou use wax to form patterns; the Bai minority workers at ZhouCheng use stitching to knot the cloth into beautiful patterns before soaking the cloth in wooden vats of natural indigo dye. The women we met doing this work were well into their seventies, had great eye sight, and have been stitching cloth for dying for over 50 years.
