The table runner I did at the Viking class is called Flip & Quilt by Carolyn S. Vagts, out of a book called Serge Smart edited by Julie Johnson, but we didn't use sergers. Ours looked exactly the same on both sides of runner when finished. You can use different material on each side. Teacher wanted us to focus on learning the technique, so she requested we do the same for both sides. Went very smoothly, came out beautiful. Would definitely need to pay attention doing two different sides. You keep adding the next piece on until it's done. Then trim edges and bind. Really amazing!
