If you like it, you can certainly use it. I personally hate the stuff. It feels icky. After a while some of it pills... little teeny tiny nylon-like pills. While quilting, it seems to shift around on the batting rather than "grab" the batting, so you have to deal with wrinkles trying to form. And then there's the iron... polyester melts so you can't iron it hot and get your piecing crisp and flat like you can with cotton.
I do like the look of gingham and don't understand WHY they can't seem to make it out of 100% cotton.
