The saris are woven from pure mulberry silk thread. The pure mulberry silk and the Zari used in the making of Kanchipuram saris comes from South India. To weave a Kanchipuram sari three shuttles are used. While the weaver works on the right side, his aide works on the left side shuttle. The border colour and design are usually quite different from the body. If the pallu (the hanging end of the sari) has to be woven in a different shade, it is first separately woven and then delicately joined to the duppata. The part where the body meets the pallu is often denoted by a zigzag line. In a genuine Kanchipuram Silk Sari, body and border are woven separately and then interlocked together. The joint is woven so strongly that even if the saris tears, the border will not detach. That differentiates the kanchivaram silk duppata from the others.
