Feel the fabric. If it feels good (that's the "hand"), buy it if the color, print, etc., are something you think you can use. One of my quilts that won Judge's choice at a quilt show is made entirely of WalMart fabric. Look for Cranston, VIP and AENathan. That is all nice fabric and when you get into a quilt it won't matter what store from whence it came.
