Not that I should be tempting you, but I succumbed to temptation in JL, today. Kingston branch has quite a few useful discounted fabrics, useful and pretty ones, not just weirdo's.
Sorry, I have beaten you to the last 2.20. metres of Robert Kaufman, Black Super Stretch Denim. It was reduced from £12.p.m. odd to £6. p.m. Curiously enough, I had been looking for a UK source online, last night without success. They had some non-stretch left and some nice jacket and blouse weight stuff.
They also had craft kits, such as the Prym Espadrilles at half price, knitting books, Bag handles, etc.
Worth a gander if you are in Kingston. Just saying....
