APPLICATIONS DOUBLE OVERLOCK STITCH

SEAMING DOUBLE OVERLOCK STITCH

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 double overlock stitch

gives strength and prevents raveling. It can be used on woven goods to replace flat or French seams. For patterns with 1/4 inch seams. 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:

The seam allowances may be trimmed to 1/4 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 “1/2”. (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 overedge method for fabrics that curl.

Note:On soft, loose knits, the fabric may seem to wave or ripple. If this occurs, reduce the pressure.

HEMSTITCHING EFFECT

By using a very large needle and a fine thread an openwork effect can be attained which is beautiful for sewing the hems into tablecloths, napkins, placemats, handkerchiefs, etc. Use a large needle, size 18 or 20. and a fine cotton thread. Tighten the upper tension slightly, until the stitch looks better on the underside than on top, (You will be sewing with your fabric face sice down.)

Turn up 1 rich then turn up 1 inch again to form a hem of a double thickness of fabric. The bulk in cor ners can be eliminated by trimming away the excess, as shown, after having folded the fabric on all sides. Stitch from the wrong side, so that the straight stitch forms on the single layer and the zigzag bites on the double layer. Stitch all the way to the edge of the fabric along all sides.
