I bought some white on white at Joanns a while back it was thin and I could hardly work with it. I went to WM and bought the same exact fabric and pattern, there was no comparison. the fabric I bought at WM was QS quality compared to Joanns. But as stated before, you have to be careful of all of thier fabric. Be sure and look to see what you are buying. Some are good some are not so good and they all say 100% cotton. Hope this helps you.
