Double sewn keyhole buttonholes
̶ keyhole buttonholes can be sewn twice on thick fabrics - use a
longer stitch length for the first run
̶ after sewing the first buttonhole, do not move the work
̶ reduce the stitch length manually and sew the buttonhole again
The slide foot must lie perfectly flat on the fabric! If the slide foot
rests on a seam allowance, the length cannot be measured
accurately.
