ADJUSTING STITCH SETTINGS
Sewing Basics

Adjusting the Thread Tension
The default thread tension, which is automatically set,
can normally be used regardless of the type of thread or
fabric being sewn. However, with some fabric and
thread combinations, the thread tension may need to be
adjusted.
■ Correct Thread Tension
The upper thread and the bobbin thread should
cross near the center of the fabric. If the thread
tension is incorrectly set, the seam may have a poor
finish or the fabric may pucker.

the fabric, press . Each press of the key reduces

Memo
If the upper thread is not threaded correctly or the
bobbin is not set correctly, the correct thread tension
cannot be set. If the correct thread tension cannot be
achieved, rethread the upper thread and reset the
bobbin correctly.
