ADJUSTING NEEDLE THREAD TENSION
Zig-zag stitching requires less
needle thre^6
tension than straight stitching.
Make a test sample with the fabric and thread
you plan to use so that you can adjust the
tension properly. The stitches should lie flat
against the fabric without causing the fabric
to pucker.
If the stitches are not flat and the fabric is
puckered, lower the needle thread tension by
turning the dial to a lower
num ber.
ADJUSTING STITCH LENGTH
Any stitch length setting from 1 to 4 will give
you an open zig-zag stitch.
The higher the
num ber,
the more open, or
farther apart your stitches will be.
The area between 0 and 1 on the dial, is used
for the adjustment of zig-zag satin* stitching, a
series of closely spaced plain zig-zag stitches
that form a smooth, satin-like surface. (Refer
to page 23 for information on satin stitching).
