Since I have started buying fabric at my local quilt store, I hate the feeling of Joann's fabrics, so I doubt I would like the WalMart fabric. I listened to a podcast on how fabrics are made, and why some are more expensive than others, and I don't think I will ever use lower or middle end fabrics again. If it is worth spending days on making a quilt, for me, it is worth using good fabrics.
