Adjust the Needle Thread Tension
for a Straight
Stitch
• Correct tension
_i_ Needle thread (Top thread)
_2_Bobbin thread (Bottom thread)
_3_ To loosen
_4_ 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
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
• Tension is too tight
_i_ Needle thread (Top thread)
_2_Bobbin thread (Bottom thread)
_3_ To loosen tension
_4_Right side (Top side) of fabric
_5_ Wrong side (Bottom side) of fabric
The bobbin thread shows through on the wrong side of
the fabric, and the stitch feels bumpy. Turn the dial to a
lower tension setting number to loosen the needle thread
tension.
