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
the stitches are evenly balanced.
When adjusting the 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

The bobbin thread shows through on the wrong side of the
fabric,
