Our ancestors pieced and quilted by hand because they had no other choice. as soon as sewing machines became available, anybody who could afford one got one. as the prices dropped, the number of quilters using machines went up.
as much as i admire hand quilting (which is a LOT) i don't feel at all guilty, nontraditional, or out of step with my ancestors when i piece and quilt by machine. i am still helping to keep alive an historic art form/process.
