Yes it is a Double Wedding Ring pattern. The Wedding Ring is made by using these -
I have sewn several strips of fabric together and then will sew them along the sewing line of the panel.
Cut each section on the cutting line and then turn with a Tube turner.
If you look closely, you can see the little hook at the end of the tube turner.
After the section is turned you press your strip sets onto your background fabric and then stitch! You can do a zig zag stitch with invisible thread or stitch close to the edge. Whichever you prefer. The Tube Turner and the Quiltsmart sheets are available at your Local Quilt shop. Or you can check online at www.quiltsmart.com. I think there are other patterns available as well.
Hope you have a Happy Quilting weekend!
