SATIN STITCH
TENSION ADJUSTMENT
Satin stitdiing requires a lighter needle thread
tension than straight stitdiing or open designs. The
wider the satin stitching the lighter the tension
required.
Wide satin stitching, Red Lever at 5, requires
the least amount of tension. For narrower satin
stitching slightly more tension should be used.
To determine correct tension setting, a test
sample should be made on self fabric using the
Special Purpose Foot. A properly balanced satin
stitdi should lie flat across the material. Any taut­
ness or puckering indicates too high a needle thread
tension.
Some soft fabrics may require the addition of a
backing to insure good stitdiing results. Crisp
organdy and lawn are suitable for this purpose.
