Please note:
- Proper setting of tension is important to good sewing.
- There is no single tension setting appropriate for all stitch
functions, thread on fabric.
- A balanced tension (identical stitches both top and bottom) is
usually only desirable for straight stitch construction sewing.
- 90% of all sewing will be between "3" and "5" ("4" is basic
setting).
- For zigzag and decorative sewing stitch functions, thread tension
should generally be less than for straight stitch sewing.
- For all decorative sewing you will always obtain a nicer stitch
and less fabric puckering when the upper thread appears on the
bottom side of your fabric.
