Abstract
A method of stitching a buttonhole in an electronically controlled sewing machine having the capability to generate a mirror image of a pattern. A first half of a buttonhole pattern is implemented which includes steps therein to return the work material to its starting position. Thereafter, a mirror image of the first half of the buttonhole pattern is implemented to provide a second half of the buttonhole which is perfectly symmetrical to the first half thereof. Additional reinforcing stitches about the cutting space of the buttonhole may be provided by the steps to return the work material to its starting position.
