Application of Ultra Stretch
Stitch
I1
A. Seaming
On most knits, a 3/16 inch finished
seam, such as stitch and overcast
or the overlock stitch, is more
desirable than a 5/8 inch opened
seam allowance. These stitches
can create a neater, more profes
sional finish, eliminate bulky seams
prevent curling, permit the gar
ment to "give" under stress, and
at the same time they cut down
on the amount of work involved
in making a garment. If ever in
doubt as to which of the
two
stitches to use, test both on the
particular fabric in question and
choose according to their perform
ance.
The stitch and overcast stitch
is excellent for stretch fabrics
such as sweater knits, bathing suit
knits, and cotton knits. It has
the greatest strength and elasticity
of all.
For patterns with 3/1 6 inch seam
allowances: Feed the fabric such
that the needle goes over the
raw edge of the fabric when it
swings to the right.
For patterns with 5/8 inch seam
allowances: Feed the raw edge of
the fabric along the etched guide
line "1/2", then trim away the
excess fabric close to the stitch
ing.
B. Procedure:
•Overlock stitching is used for
seaming and finishing the cut
edge of knit fabrics, all in one
operation.
•This overlock stitch is especially
good for stretch fabrics such
as double knit and jersey and
will give a firm, neat edge finish.
