TOP THREAD TENSION
Loose
Tight
- Basic top thread tension setting: “4”
- To increase the tension, turn the dial to the next number up. To reduce the tension, turn the dial
to the next number down.
- Proper setting of tension is important to good sewing.
- There is no single tension setting appropriate for all the stitch functions and fabrics.
- 90% of all sewing will be between “3” and “5” (“4” is basic setting).
- For all decorative sewing you will always obtain a nicer stitch and less fabric puckering when
top tension is reduced by 1 number so the upper thread appears on the bottom side of your
fabric.
