My Mom just got back from India .. she said so many fabrics are of mixtures we don't see here ... like cotton and silk blends are quite common. Do pretest all of your fabrics for color fastness and reaction to water.
Peggy Toole a fabric designer for Robert Kaufman had a line of fabrics called "Jewels of India" it is spectacular...The Kaufman web site shows patterns for using that line, and might provide some inspiration.
