    [Cause/remedy/check details]

    The upper threading is incorrect.
    Return the upper thread tension to the standard setting, and then refer to Tangled thread on wrong side of fabric to correct the upper threading.

 

 

2. Check that a needle and thread appropriate for the fabric are being used.

The sewing machine needle that should be used depends on the type of fabric sewn and the thread thickness.

If a needle and thread appropriate for the fabric are not being used, the thread tension will not be adjusted correctly, causing wrinkles in the fabric or skipped stitches.

Refer to Combination of fabric, thread and needle to check that a needle and thread appropriate for the fabric are being used.

 

 

3. Select the appropriate setting on the thread tension.

The setting selected for the upper thread tension is not appropriate.
Adjust the upper thread tension to select an appropriate thread tension.

  • For details, refer to How to adjust the thread tension to select an appropriate thread tension.
  • The appropriate thread tension differs depending on the type of fabric and thread being used.
    Adjust the thread tension while test sewing on a piece of scrap fabric that is the same as that used in your project.
