I have found that quilting in sections works very well if you're using your regular sewing machine. Look at the way you can divide the quilt into sections that will fit and will be easy to work with. Divisions do not have to be of equal size. Marti Mitchel's book is my most usable reference as to how to work it out. I've been very satisfied that now I don't hesitate to do a king sized quilt.
