In this project pulled from the pages of Leni Levenson Wiener's widely popular book, 3-Fabric Quilts, you'll learn just how easy it is to quilt something wonderful. What make this Op-Art inspired quit project so much better than others? Most op art quilts require every corner of every square to be precisely pinned and matched. But not this one! Make a strip set, cut it up and reassemble the strips for a great op art design.
