GUIDING AND SUPPORTING FABRICS
Most fabrics need to be guided only 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 apply gentle tension on the seam by holding
fabric in front and in back of the presser foot.

PRESSURE ADJUSTMENTS
To decrease pressure, turn thumb
screw up.
• To increase pressure, turn thumb
screw down.
Pressure is the force the presser foot exerts on
the fabric.
Too light a pressure will cause irregular feed
ing, 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 weight and texture of
the fabric, must be considered when determining
the amount of pressure needed.
