Just spoken to a friend who went to Bombay/Mumbi, and she said that there are dress fabric shops & department stores with good haberdashery/fabric sections. Silks, cottons - plain & woven patterns & embroidered fabrics of all sorts. If you go for saris you will get about 6 yds x 43"(ish) of fabric, with a woven border down each selvedge, and a woven pattern across one end of approximately 1 yard, some of them have a section of less dense pattern, and then the rest is plain (just measured a sari length I own).
