I have a brother pq1500s on a queen size grace start right frame and I love it. To get around the problem of shrinking throat space near the bottom of a quilt , for quilts that are longer than they are wide ( like a twin size ) I just load it in sideways instead of top to bottom. For all over designs this really is not an issue , for more detailed designs I have to think a bit more on the layout but makes it alot easier when I get to the end !
