STRAIGHT STITCHING
For straight sewing on fine fabric or very soft material, you
may want to use the straight stitch presser foot included in your
accessory box.
(A) Loosen thumb screw and remove zigzag presser foot.
(B) Replace with straight stitch presser foot.
Be sure to set the zigzag width knob at 0, or the needle will
break in striking the presser foot.
CREATIVE EMBROIDERY
Be sure zigzag presser is in place.
Tne satin stitch which is really just a very short zigzag stitch
and the basts for most embroidery, is obtained by setting stitch
length as near 0 as possible without stopping the feeding action
and zigzag width at 5.
To stitch continuously at one width of zigzag stitching, set
zigzag width dial to chosen stitch width number.
With the machine set for a short stitch length, different designs
can be made by turning the zigzag width dial back and forth
between 0 and 5 or any other combination of widths.
Set a rhythm for yourself and then proceed. After awhile you
will become quite skillful, varying your designs by the speed of
the machine, stitch length, and manipulation of the zigzag width
knob.
