Until recently I purchased only LQS fabric for my most important quilts. But with the rising cost of fabric everywhere I have had to modify my rules. Even Joann's is getting a little pricier. Now I sometimes purchase, very carefully, at Joann's and Hobby Lobby. I still won't buy any fabric that is thin or rough feeling. With all the work we put into our quilts, we want them to last as long as possible.
I read recently that the cost of cotton is going down since the weather has been very good where it's grown. I don't know how true that is, but I don't see the cost of cotton fabric going down yet. Maybe it never will.
