The very first quilt I FMQed on my Bernina was a 24 X 36 lap quilt. I made a large daisy in each square. Certainly not densely quilted. It took me about a half hour. Since then I've done a few king size and a few queen size, but didn't keep track of the time. If my quilt is really big, sometimes I get nervous (especially if there is a deadline), so quilt them by check.
I have found that the easiest way to do FMQ on a large quilt is to GLUE it. It holds together, seems like it's one layer of fabric, and you can start on the outside and work in.
