GUIDING AND SUPPORTING FABRIC
Most fabrics need only to be guided in front of the presser foot.
Fabrics of unusual texture and weave, filmy sheers, crepes, knits, tricots, etc., require support while
being stitched.
For such fabrics, use the straight stitch throat plate and presser foot, and apply gentle tension to the
seam by holding the fabric in front and in back of the presser foot as illustrated.

PRESSURE ADJUSTMENTS
Decrease
Increase
To decrease pressure, turn thumb screw upward.
To increase pressure, turn screw downward.
Pressure is the force the presser foot exerts on fabric while it is
being stitched.
Smooth, even handling of several thicknesses of fabric results when
pressure is correctly regulated.
Too light a pressure will result in irregular feeding which affects
both quality of stitch and evenness of seams.
Too heavy a pressure not only affects stitch and seam quality but
will mar smooth surfaces and pile fabrics.

Surface finish, as well as the weight and texture of the fabric, must
be considered in determining the amount of pressure needed.
