I've had no experience with that supplier but the silks look lovely.
Seven years ago I made a wedding dress and jacket using this supplier http://www.ahimsasilks.com/
The bride was active in the Indian charity sector so it was nice to find a supplier who matched her interests. I think they had a greater range of qualities and weights back then.
My go-to local-to-me supplier for silk is the great James Hare in Leeds http://james-hare.com/
