I have quilted many queens on my Bernina. It can be done but takes some organization. I divide the whole thing into 3 sections and sandwich all three layers separately, then pin and baste the layers I then quilt each section. It does take some organization and planning but it can be done. When you are quilting each section you want to free motion up to about a half inch of where the connecting seam would be. You'll then turn it over and pin the bating and backing back out of the way and sew the front seam on the machine. Then hand sew the batting together, then the backing. When finished it will look just like all one piece. This is the way I have found to be the most successful to mel I'm sure there are other methods But doing it yourself saves you money and is rewarding. I hope I have explained it.
