Impressive!
I only discovered BST two weeks ago when I was searching for some of the same fabric that my work trousers are made from (bengaline apparently)!
I ordered some. It arrived within 2 days of the order. I ordered some more... again it arrived in two days! The fabric is great quality, super speedy delivery and the prices are oh so reasonable. I was previously wishing I'd known about the shop when I lived up that way, but now I'm thinking it's best that perhaps I didn't, if only for the sake of my bank balance.
