How to adjust the thread tension
You may need to adjust the thread tension depending on the fabric and thread being used.
To achieve attractive results when sewing your project, correct tension is an important point. Too much or too little tension will weaken your seams or cause puckers on your fabric.
The upper thread and the bobbin thread should cross near the center of the fabric.
Only the upper thread should be visible from the right side of the fabric, and only the bobbin thread should be visible from the wrong side of the fabric.

The upper thread tension is changed using the thread tension dial.

Since the results differ depending on the type of stitching and the number of layers of fabric sewn, perform the trial sewing under the same conditions that will be used with your project.
If the bobbin thread is visible from the right side of the fabric, the upper thread is too tight.

If the bobbin thread was incorrectly threaded, the upper thread may be too tight.
In this case, refer to "How do I install the bobbin wound with thread?" and rethread the bobbin thread.
Turn the thread tension dial counterclockwise to loosen the upper thread tension.
If the upper thread is visible from the wrong side of the fabric, the upper thread is too loose.

If the upper thread was incorrectly threaded, the upper thread may be too loose.
In this case, refer to "How do I thread my machine?" and rethread the upper thread.
Turn the thread tension dial clockwise to tighten the upper thread tension.
If the upper thread is not threaded correctly or the bobbin is not installed correctly, it may not be possible to set the correct thread tension. If the correct thread tension cannot be achieved, rethread the upper thread and insert the bobbin correctly.
For details, refer to "How do I thread my machine?" and "How do I install the bobbin wound with thread?".
