Which Walmarts sell fabric? How can I find out?

I'm desperate to find a few fabric patterns I bought in February at Wal-Mart because I didn't buy enough for my quilt and need a little more of 5 of them. They aren't at my Wal-Mart so I thought I would check at others. Is there some way I can find out which ones sell fabric (to save going to a bunch that don't)? I can't think how else to search for them because I don't even know the brand names! Thanks for any tips!
