Applications
Ungerle Seams
To make a lingerie seam durable and
flexible, use the plain zig-^ag stitch at a
narrow width setting. This seam treat-
rnent
is particularly suitable for bias
seams. When seaming nylon tricot,
insert a Style 2046 needle in the
mactiine.
» Straight stitch the seam on wrong
side of fabric.
» Press both seam allowances in the
same direction.
» From the right side, topstitch with
narrow zig-zag stitch, letting the
needle alternately enter the seam line
and the seam thickness.
Satin Stitching
Satin stitching, a series of closely
spaced zig-zag stitches that form a
smooth, satin-like finish, illustration A, is
useful for both practical and decorative
work. Decorative stitch patterns can be
sewn at satin-stitch length.
Set your machine for desired stitch.
Adjust stitch length for satin stitching:
stitch width in narrow to medium range.
Adjusting Stitch Length
® Run machine at slow speed,
e Gradrjally adjust stitch length from 4
toward 0 until stitches are closely
spaced and form a smooth surface.
Adjusting Upper Thread Tension
Satin stitching usually requires less
tension than straight stitching and open
zig-zag stitching. Furthermore, the wider
the satin stitch, the lighter the tension on
your thread must be. Notice the stitch­
ing on your sample. If the fabric is
puckered, illustration B. or the lower
thread is pulled to the fabric surface,
lower the upper thread tension by
turning the dial to a lower number.
