Thread tension
To obtain a perfect seam appearance and durability make
sure the needle and bobbin thread tensions are correctly
adjusted with regard to each other, i.e. the threads evenly
meet between the two fabric layers.
The following is valid for general sewing:
Bobbin thread is visible on the top side of the fabric:
The needle thread tension is too tight or the bobbin thread
tension is too loose.
The thread tension must be corrected.
Top thread is visible on the underside of the fabric:
The needle thread tension is too loose or the bobbin thread
tension is too tight.
The thread tension must be corrected.
For decorative stitches and buttonholes the top thread
should be visible on the underside of the fabric.
