I have found decent fabric at Wal-Mart and I have felt crappy fabric at Walmart. That being said, I think that you should buy the best you can afford for the project you are designing. My mom used many types of fabric when making her scrappy quilts. These quilts were made to stay warm and some of them are in use to this day. (And she's been in heaven for 8+ years. I tend to use LQS or Joann's, Hobby Lobby and Hancock's. Depends on situation.
