12. Checking the Thread Tension
Check the embroidery to see if it was sewn with the correct thread tension. If the thread tension is not
adjusted correctly, the stitching may be uneven or there may be puckering in the fabric.
Correct thread tension
From the wrong side of the fabric, the bobbin
thread should be about one third of the stitch
width.
1 Right side
2 Wrong side
If the embroidery appears as shown below, the
thread tension is incorrect. Correct the thread
tension.
1 Right side
2 Wrong side
The tension of the upper thread is too tight,
resulting in the lower thread being visible from
the right side of the fabric.
Loosen the tension dial by turning the dial
counterclockwise.
1 Right side
2 Wrong side
The tension of the upper thread is too loose,
resulting in a loose upper thread, loose thread
locks or loops appearing on the right side of the
fabric.
Tighten the tension dial by turning the dial
clockwise.
For details on adjusting the thread tension, refer
to “Adjusting the Thread Tension” on page 112.
Note
In this tutorial, the thread tension was
checked after embroidering was finished.
However, normally, embroidering should
be temporarily paused and the thread
tension should be checked after the first
100 stitches of each color sewn with each
needle bar.
The resulting embroidery may not appear
as expected, due to the type or thickness
of the fabric being sewn or to the type of
stabilizer material used. Be sure to sew a
trial embroidery before sewing on your
project.
Memo
In the built-in embroidery patterns, one
pattern is used for checking the thread
tension. For details, refer to “Checking the
thread tension of built-in patterns” on
page 217.
