I can think of two things. The first is best of show awards for quilts that are machine sewn and quilted. Hand quilting purists who do not use sewing machines or long arms feel that there should be separate categories for hand quilters and machine quilters (this may have been resolved for all I know since I haven't attended any national shows). The second thing that seemed to set this board on fire was the Kill Sunbonnet Sue quilt from the seventies.
