Oh, you're NOT a beginner! Really! Confess and we will forgive you! LOL! That quilt is a real stunner. You should be sooooo proud. I hope that link from yonnikka helps. There is a way to do the backing so that you don't have the seams straight up the back -- it just looks more professional. There is a way that you create a tube and then split the tube, but I can't seem to find the link for it today. Keep up the good (great) work.
