Don’t be too discouraged by the bad experience with a who knows who purchase from Amazon. There are many reputable shops online that sell quality fabric. I do encourage you to look at Thousand of Bolts. And Missouri Star Quilt Company. And Jordan fabric. Any e-quilters. And quilt in a day. And many more.
