Bar tack stitching
Bar tacks are one type of reinforcement stitching
used to strengthen points subject to strain, such as
pocket corners and openings.
As an example, the procedure for sewing bar tacks at
pocket corners is described below.
a
Determine the desired length of the bar tack.
Set the button guide plate on buttonhole foot
“A” to the desired length. (The distance
between the markings on the presser foot scale
is 5 mm (3/16 inch).)
