They certainly can. I can't afford one, and don't have the space so I have a Janome 6600, which allows me to quilt most things with relative ease, although I need to make a great many pauses to shift things around. On the other hand, my guild owns a factory recondidioned LA. Generally it takes my guild sisters about 3 hours to do a fairly good ( not professional) job on a full sized quilt. I certainly can't say that, but I can't stand long enough to do a quilt.
