Use this stretch stitch with knitted fabric
and other fabrics that stretch. Sew as
you do with regular straight stitch
seaming. The seam may be pressed open
as with any regular seam, but will stretch
if necessary.
This is also a good stitch to use on curved
seams regardless of the type of fabric.
Any seam that will receive a great deal of
strain when worn should be sewn with
the stretch stitch. Use in children's shorts
and slacks as well as adult sports clothes.
