Standard buttonhole with gimp
thread
To sew especially durable buttonholes,
on heavy fabrics, knits or sportswear, we
recommend using a gimp thread.
On knits the gimp thread is particularly
important to prevent the buttonhole from
stretching.
• Lay the gimp thread over the rear
protrusion A and pass the thread ends
B
underneath the presser foot towards
the front.
• Clamp the threads to the left and right
of protrusion B.
• Slide the buttonhole runner as far
forward as possible and sew the
buttonhole as described.
• Pull the loop of the gimp thread into
the buttonhole and cut the threads.
