All my king size quilts are QAYG, no sashing. The 6 rows are about 18" wide (so the backing is cut on the fold and 22" or less), with row 1 and 6 having an added 4 inch boarder. Some creativity is required that I wont go into. I use this method whether I am hand quilting or FMQ. After quilting, sew the rows together with 1/4" seams, trim batting to touch, heat tape or cross stitch the batting, and hand sew the backing. The one negative that might bother you is the boarder on the side is cut at the 18" mark, It has never bothered me.....again there are many creative ways to deal with it if it does bother you. And, FYI, I hate sashing on quilts, in general.........
