I buy JoAnns fabric, flannel and muslin there. I made a lot of quilts and have done so for 25 years. I believe a person has to look at each fabric line and what they intend to do with it. I have bought from quilt stores, JoAnns, Hobby Lobby, WalMart - I guess all of them. I don't have any bad experiences to share because I really have not had anything awful happen. I do not prewash or preshrink anything because I love the wrinkly, antiquey look that I get when I pull my latest creation out of the dryer. My sister can't bring herself to buy anything from JoAnns as she is convinced it will not hold up even though I haven't ever had that experience. I will say that if the only place I could buy cotton to make a quilt was from a quilt store, I would have given up the craft a long time ago. I think LQS and JoAnns really help support each other in that regard and I'm just thrilled there are so many places to purchase fabric.
