A Seams
The normal stitch length for most
fabrics is 3, but the length chosen
should depend on the fabric and
area of usage. Usually, heavier
faarics require longer stitches, and
lighter weight fabrics require
shorter stitches. For curved seams
and bias cut areas use a shorter
stitch length to add strength and
elasticity to the seam.
