Just finished a prayer shawl using James C Brett Marble Chunky yarn. Thanks to Johnny Vasquez at New Stitch a Day, I learned how to do the Roman Stripe Stitch. He has THE BEST tutorials! The shawl is a combination of the Roman Stripe and stockinette stitch and contains a great palette of colors and texture.
