I have the SQ9185 machine and I've quilted 2 lap size (45x80) and currently working on my 3rd. It is doable. I also straight line and a few decorative stitches. At first I did the push and shove method through the harp. It really wasn't that hard. I now roll up and it fits perfectly with no problems. I do, however, use a low loft batting. Pelons Natural with scrim.
