When I quilted my queen size on my domestic machine, I laid the top, wool batting and backing together, but pinned only the centre section. Before starting to quilt, I cut my batting into 5 sections . I started quilting at the centre section where it was pinned. When I got close to the edges, I stopped, refastened another piece of batting, quilted that and the reattached the third piece of batting until I was finished. It worked really well since I wasn't always working with the bulk of that batting. This technique is from a Marti Mitchell book. If you wish, pm me.
