SATIN STJTCH
TlìNSION ADJUSTMENT
Satin stitching letjuircs a lighter needle thread
tension than straight stitching or open designs. The
wider the satin stitching the lighter the tension
reguired.
Wide satin stitching, Stitch Width at 5, requires
the least amount of tension. For narrower satin
stiIdling slightly more tension should be used.
To detonnine eoiicet tension setting, a test
sample should be made on self fabric using the
Special Purpose Foot, A properly balanced satin
stitch should lie flat across the material. Any taut-
ncss or puckering indicates too high a needle
thread tension.
Some soft fabrics may rccpiiie the addition of a
hadcing to insure good stitching results. Crisp
organdy and lawn arc suitable for this purpose.
