Adjust the NeedleThread
Tension
for Straight
Stitch
• Correct tension
_1_ Needle thread (Top thread)
Bobbin thread (Bottom thread)
To loosen
(_ To tighten
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 needle 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 right side (Top

lower tension setting number to loosen the needle thread
tension.
