Thank you all for advices. Katrine, I will check out all the links.
Odessa, you spelled it right , it is Rue de Steinkerque ! I found it on the map ! Thank you !
Those shops have all types of fabrics, not only for quilting (in fact, in just one shop I found some batiks with 20 euros per yard !).
When I was there 3 years ago, I was interested only in quilting fabrics , now I am curious if I can find some nice fabrics for bags.
