Buttonhole foot with slide  for four-step buttonholes:

• Mark the position and length of the buttonhole on the fabric.
• Position the fabric underneath the foot and insert the needle at the start of the buttonhole.
• Lower the foot, making sure that the slide is in the rearmost position (the two markings must meet).
• Sew the buttonhole, selecting the next step of the buttonhole at the relevant markings.

Important: Always sew a test buttonhole.
