Abstract
In a sewing machine for creating buttonholes, a selection switch is used to designate whether the hole will be cut first or the buttonhole will be defined by stitching first. In both cases, stitch width remains constant. Where the buttonhole is outlined by stitches first, a needle bar bight line is offset by a distance .DELTA.X from the bight line followed when the buttonhole is cut first. The result of the .DELTA.X offset is a spacing equal to 2.DELTA.X between the inner edges of the stitched buttonhole providing space in which to cut the buttonhole.
