I know a lot of quilters prefer to use only top of the line fabrics, and that's fine. Some of us make a lot of "utility" quilts or for kids that will get dragged around, washed thousands of times, and maybe played with outside. For those quilts, I use what I "feel" is good for the project. That includes WalMart and Joanne fabrics. You have to be personally happy with the fabric that you put into your quilts. A quilt made with lesser ($6-8 per yard) fabrics will be just as loved as one you spent $10+ per yard on.
