Wal-Mart seems to be phasing out the fabric departments in most of their locations, Word has it that when they remodel a store, the fabric dept is eliminated. I have found some good fabrics there abd much cheaper than JoAnn's prices.
Watch the ends of bolts to see where fabric are made. Most are coming from China and Japan. Handle the fabric and open it to single thickness. Some has so much dye it appears like a thick coating that is rolled on gauze.
Regardless of where you shop, be aware of what the quality of the fabric is and if you would be satisfied with using it for your quilt.
A few months ago Patrice told us that only a few textile mills are still producing fabrics in the US. Patrice, correct me on this one please! Good quality is difficult to find at an affordable price.
I will be interested to hear what others have to say on this subject.
