I, too, have purchased lesser quality fabric that is still in my stash. I wouldn’t throw yours out. I plan to use mine to practice FMQ and ruler quilting as much of it consists of fat quarters. I’ll probably end up making a lot of placemats, dog/cat quilts and possibly some bags. I have mixed quilt shop fabric and Joann’s fabric in a couple quilts when I was limited in budget. Both quilts are still in use and holding up fine so far. Even if the cheaper fabrics break down, I’ll be happy to make new quilts for the recipients.
