Welcome Mags, you will find this site to have very helpful and friendly quilters to ask for and get advice. Have you looked at the Quilt in a Day site for Eleanor's tutorial for a double wedding ring, as I think her technique may make the quilt easier to put together. I used her techniques when I did a Dresden Plate quilt and I found it much easier to add the center circle using fusible interfacing. Don't let anyone tell you that you are crazy for tackling a more challenging quilt - when I first started quilting many years ago, I usually went for more intermediate and sometimes some challenging quilt patterns and I was pleased with the results, so step out of the box, you'll be amazed at what you'll be able to do.
