The ideal straight
stitch has threads
locked
between
two layers of fabric,
as illustrated
(magnified
to show
detail).
If you look at the top 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

of fabric layers
