Stitch Length Selector
To Tighten
Adjusting Stitch Length
The stitch length
selector does two
jobs : it controls
the number of
stitches per
inch, and it lets you sew
either forward
or in reverse .
The numbers
on either side of the
selector
represent the number of
stitches per inch : the higher the
number, the shorter the stitch, .
Gen-
erally, shorter stitches are
best for
lightweight fabric ; longer ones
for
heavy fabric . The FINE area, which
represents over 20 stitches
per inch,
is used for zig-zag
satin stitching
only .
