Note:
In
general,
fine
threads
and
needles
are used
for
sewing
thin
fabrics,
and
thicker
threads
and needles
are
used
for
sewing
heavy
fabrics.
Always
test
thread
and
needle
size
on
a
small
piece
of
fabric
which
will
be
used
for
actual
sewing.
*Use
the
same
thread
for
needle
and
bobbin.
*When
sewing
stretch,
very
fine
fabrics
and
synthetics,
use a
BLUE
TIPPED
needle.
The
blue tipped
needle
effectively
prevents
skipped
stitches.
*When
sewing
very
fine
fabrics,
sew
over
a
piece of
paper
to
prevent
thread
distortion.
