Tie and Dye is one of the oldest textile techniques where portions of cloth are tightly tied before dyeing. These resist the dye and form the pattern. In India, the specialized skill of ikat weaving exists in three areas, Orissa, Andhra Pradesh and Gujarat. The Patola from Patan in Gujarat is especially well known. In a double ikat silk sari, both the warp and the weft are separately tied and dyed so that they blend perfectly when woven and give the textile its rich colour and form. There are other forms of tie and dye but unlike ikat these are not pre loom process where only the yarn is resist dyed. Bandhej, the tie technique includes bandhinis of Gujarat and Rajasthan.
