ADJUSTING STITCH LENGTH
The stitch length dial controls the length of
stitches. The numbers around the edge of the To Shorte,.0B To Lengthen
dial express stitch length in mm; the tower the
1
number, the shorter the stitch. Generally, shorterI&
stitches are best for lightweight fabric, longer
stitches for heavy fabric. The area from 0 to 1
is used for the adjustment of zig-zag satin
stitching (see page 22).

NEEDLE-THREAD TENSION
Reverse Stitch Push Button
Correct tension is important because too much
-----------------------
or too little will weaken your seams or cause
your fabric to pucker. Make a test sample with
the fabric and the thread you plan to use and
examine it. A well balanced stitch, as !shown in
illustration A, will have the needle and bobbin
threads locked between the two layers of fabric
with no loops on top or bottom and no pucker.
The tension dial regulates the degree of ten-
A
sion on your needle thread. Set it according to
the type of thread and fabric you use. The num-
bers on the dial eliminate guesswork.
If the fabric puckers 8, decrease tension. If the
'
stitches in your test sample look loose C, in-
/6
crease needle-thread tension. ~
" To decrease tension, turn dial to lower num-B
ber.
* To increase tension, turn dial to higher num-
be r.
