Can the Singer Slant-o-matic 401A create buttonholes, and if so, how?

Yes, the Singer Slant-o-matic 401A can create buttonholes. To establish the correct stitch setting and length of the buttonhole, a sample must first be made. Three Red Lever settings are available, and the fabric weight will determine the selection. The length of the cutting space for the buttonhole is measured by the width and thickness of the button. The finished buttonhole length will be the cutting space plus 1/8 inch for bar tacks. It is recommended to work a sample buttonhole in the same fabric as the garment, using a double fold and including interfacing if used. For the stitching procedure, set the Selector and Red Lever as needed. Place the work under the needle, aligning the center marking of the buttonhole with the center score line of the foot. To form side stitching, turn the hand wheel toward you so the needle enters the fabric at point A. Lower the foot and stitch to the end of the marking. Leave the needle in the fabric at point B, raise the foot, and pivot the work on the needle. Lower the foot and take one stitch without changing the Red Lever setting, bringing the work to point C. Adjust to the Red Lever setting for bar tacks and take at least six stitches, stopping at point D. Readjust to the Red Lever setting for side stitching and complete to point E, or approximately six stitches from the end of the buttonhole. Move to the Red Lever setting for bar tacks and duplicate the tack previously made, ending at point F. For raised or corded buttonholes, #8 pearl cotton and buttonhole twist are suitable filler cords. Place the spool of filler cord on the second spool pin. Carry the cord through the first thread guide, straight down between the center and back tension discs, into the large thread guide, and then through the eyelet on the Special Purpose Foot. Draw the cord under and in back of the foot and proceed as for regular buttonholes. To secure stitching, move the Red Lever to #1 setting and take three stitches. Remove the work, draw threads to the underside, fasten, and trim. Cut the opening for the button with sharp embroidery scissors.
