Adjust the NeedleThread Tension for Straight

The ideal straight stitch has threads locked between two
layers of fabric, as illustrated (magnified to show detail).
If you look atthe top and bottom of aseam, notice that
there are no gaps. Each stitch is smooth and even.
When adjusting needle thread tension, the higher the
number, the tighter the needle thread tension.
Results depend on:
-- stiffness and thickness of the fabric
-- number of fabric layers
-- type of stitch
