The ideal Straight stitch has threads
locked
between
two layers of fabric,
as illustrated
(magnified
to show
detail).
If you look at the needle and bottom
of a seam,
notice that there are no gaps.
Each stitch is smooth
and even.
When adjusting
needle thread tension,
the higher the
number, the tighter
the top thread
tension.
Results depend
on;
stiffness
and thickness
of the fabric
number
of fabric layers
type of stitch
e Tension
is too tight
O Needle thread (Top thread)
Bobbin thread (Bottom thread)
(_) To loosen
(_ Right side (Top side)
_) Wrong side (Bottom side)
The bobbin
thread
shows through
on the right side
of the fabric and it feels bumpy.
Turn the dial to a
lower tension
setting
number
to loosen the needle
thread
tension.
