I shop at JoAnn's a lot, and have never had an issue with their fabrics...I am not obsessive about my fabrics, but I also don't accept low quality fabrics. I think most of their fabrics are just fine for "regular" quilts. If making a true "family heirloom" quilt, yes, I would buy more expensive fabrics. But for general use quilts, in my opinion their fabrics are just fine. Never had one come up with spots or other blemishes...maybe just that one line was not too good. I would have taken them back to the store.
