I have one backing but wanted to quilt 2 table runners at the same time. It took a few attempts to get everything set up properly. I left 4 inches in the middle between the runners. There's plenty of space on the backing on the outer sides of the runners. I loaded the same as I would any quilt. I pinned the bottom edge to the leaders but each table runner was pinned as a separate quilt.
I'm quilting each runner exactly the same. I thought ribbon candy would look good in the borders. Each of the triangles has arcs quilted on each side. The flying geese has 3 echoed arcs per short side. The longer piece made by the flying geese and triangle just has lines following the shape of the that piece. I was hoping it would convey some movement. Anyways, now that all the quilting has been decided, I just have to repeat these motifs until the runners are done. I like it and will work on it a little bit at a time. It shouldn't take too long since these table runners aren't too big. I'm using a very light grey Aurifil thread.
