I use a 24 inch hoop on all my quilting and have made numerous king sized quilts. I start in the center and quilt toward the sides. Seems to work great for me. Just have to be sure to pin the sandwiched quilt well so it doesn't shift when I move it around. I'm starting to have neck and shoulder pain from arthritis so just make sure that I get up and move around frequently and usually try to rest the hoop on something so I not holding the weight of the hoop and quilt up with my arms.
