There is another alternative to 'QAYG. Today, I found a Marti Mitchell book, 'Machine Quilting in Sections' that was originally published in 2004. I think it has been republished, because it was at my local JoAnn's which hasn't been open that long! Anyway, Marti shows a BUNCH of ways to tackle machine quilting big quilts. She shows various ingenious ways of NOT joining all the blocks together until the quilting is finished. Many of them have the borders added and quilted AFTER the rest of the quilt is finished.
