Correct and wrong thread tension
In
order
to
easily understand
the importance of
correct thread tension,
you can try different thread
tensions
by
sewing
two
thicknesses
of a
scrap of
cloth. Begin by using an
excessively
loose tension,
i.e. you turn the upper thread
tension
dial upwards
as
far
as
it
will go.
Look at the cloth and you
will
find the lower thread lies straight and the
upper
thread
is
drawn down
into
the lower
side
of
the
cloth.
If
you turn the dial downward, the
opposite
occurs.
The upper thread lies straight and
the lower
thread cones
up
in
loops
on the top of the
cloth.
The thread tension is
correct when the threads inter-
lock
in
the middle
of
the
layers
of
cloth.
Before
starting
to
sew,
check
the
tension
by
sewing
on
a
piece
of
the
same
fabric you intend to work with.
Before you begin to
use
the
zj+-zag
stitch, check
that the thread tension is the same as when
you
did
straight stitching. Use
a
scrap
of
material
to
see
how
the
zig-zag stitches look
if you
set
them
first
on
the
loosest (upper picture), then
on the
heaviest
thread tension (middle picture). Then finally
the
correct thread tension
will
look about
like that
in
the lower picture.
