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.
