I have done several throws (approx. 45 x 60) on my Featherweight. Am about to tackle a twin size in the next few weeks. Anything larger that I've done has been hand quilted. Now I have made an extra long adult sized hooded cape out of thermal backed drapery fabric and lined with velvet on it as well. So you can scrunch up a lot more than you would think you could into such a small space.
