I think some of the better quality quilting cottons at Joanns are not bad, but you really have to watch it if you get the keepsake calicos. More than once I've found flaws in the yardage once I get home. I try to watch for flaws as they measure, but I don't always see them at that point. I buy a lot at the LQS, but buying backing fabric at the LQS can get really pricy. I too have to feel the fabric before buying--if it feels cheap or thin, I pass it by.
