SEAMS
This stitch gives a finished 1/4 inch seam
in one step. For knits, it gives strength
and elasticity to the seams and prevents
the curling of the fabric that often occurs
with 5/8 inch opened seams. It is most
applicable to soft, thin knits such as
nylon or acetate knits, but may be used
on other fabrics as well. Always make
test seams with this stitch.
For woven fabric, the overlock stitch
gives strength and prevents raveling. It
can be used on woven goods to replace
flat felled or French seams.
For patterns with 1/4 inch seams:
(Fig. 107) Place the raw edge of the
fabric under the presser foot so that as the
needle swings to the right, it comes down
at the raw edge. This will result in an
enclosed seam allowance.
For patterns with 5/8 inch seams: (Fig.
108) The seam allowances may be trimm­
ed to Vi inch either before or after sewing.
If trimming before sewing, proceed as
above. Otherwise, sew the seam with the
raw edge of the fabric on the etched guide
line (Any time you use the full
width of a particular stitch, you should
readjust the raw edge of the fabric
1/8
inch to the left.) Afterward, trim the
excess fabric near the stitching. This
method is actually easier than the over-
edge method for fabrics that curl.
/vore.' On soft, loose knits, the fabric
may seem to wave or ripple. If
tnis occurs, reduce the pressure.
