I've only done 4 quilts that I can think of that aren't at least twin sized, 3 were baby quilts and one is a lap quilt. I usually do them queen size. I just have this mindset that I am making them for beds so, they need to be large.
I recently got a long arm so I don't have to have them quilted by someone else and someday I'll be good enough to do my "better" quilts.
