Le Rouvay is indeed permanently closed- the original owner passed away and the family wasn't interested in keeping the business. I was lucky enough to visit last October shortly before they closed. It was a cute and friendly place, but as others have said, the quilting fabrics were all American companies- I bought a few fat quarters just for the fun of it, but they were Windham fabrics

I have found the same situation in Germany and Italy, "Patchwork" is very much an American thing and the fabrics, patterns, books are basically the same as what we have, but much more expensive. I tend to get my fabric fix in the outdoor markets, antique linens and even beautiful kitchen towels, etc. are different from we have here and much more affordable!
Have a wonderful trip!
