double sided quilted fabric

[dunwerkin]

Does any sewer - that's someone who sews, not the unsavoury option, know of anywhere in the UK, preferably an internet seller, who supplies double-sided pre-quilted fabric? Its readily available in the States, but I am not planning to go - specially just to spend even more money!
If you can help me out, it would save a lot of frustration looking at overseas web sites. Thanks in advance.
