I don't know how many have come across The Millshop Online.
I've been searching for curtain fabrics for most of my windows and found something I really liked in, I think, Just Fabrics. £12.95 a metre wasn't too bad a price but I kept searching other sites for other fabrics. Then the one first wanted was in The Millshop Online for £9.95 per m. Since I wanted 12m that was a decent saving. The fabric arrived quickly and was well-packaged. I have now ordered from them again. P&P is £8.95 though free over £125. Samples are free. They also do upholstery fabric.
