^4. APPLICATIONS OF THE ELAS

TIC OVERLOCKSTITCH

This stitch is very effective for overcasting,
édgestitching, etc, on knits and very stretchy
fabrics, also, for decoration.

TOPSTITCHING

A decorative topstitch can be produced with
the elastic edging stitch. Stitch around the

structural lines of the garments for a dramatic
effect. Topstitch a braid or decorative inset
with the elastic edging to add an additional
decorative flair.
Pattern: AA

Length: 5

Width: 5

Feed Dog: Up

Pressure: Normal

Foot: Embroidery

Needle Position: L or R

EDGING

As with the stretch blind hem, the elastic
edging stitch can be used for a decorative
edge on place mats, napkins and tablecloths.
Proceed as you would with the stretch blind
hem stitch, but use the elastic
edging stitch instead.

Pattern: AA

15. APPLICATION OF RICK-RACK

A. Topstitching/Rick-Rack
A decorative topstitch can be produced with
the rick-rack stitch. Stitch around the struct
ural lines of the garment tor a special effect.
Topstitch braid or a decorative inset to add
an additional creative flair.

B. Tapering/Rick-Rack
The rick-rack stitch may be tapered to form
creative stems and petals of flowers, embro

idered pictures and wall hangings. As in
tapering the zigzag, slowly turn the stitch

width lever from 0 to 5 and back to 0. A

group of these tapered rick-rack stitch will

form bouquet-like effect.

C. Procedure:

• The elastic rick-rack stitch is a zigzag
line of stitching that is desired so that seams

may be pressed open.

■ Apply this stitch to areas of stress on both
wovens and knits.

• Use narrow width of zigzag as a heavy duty
triple stitch for seams.

• Use medium and wide widths of zigzag for

overcasting edges of seams, facings and
hems of heavier weight fabrics such as
terrycloth, and for attaching elastic. Use
also for decorative stitching.

• Guide your fabric from the front. Do not
pull or push as it will cause poor stitching.

STHETCH SEAMS

A ball-point needle is essential.

Paper may be laid under knits for smoother

feeding.
(a) Medium-weight fabrics-

double knit jersey.
Apply elastic triple stitch.

(g) Light-weight fabrics

Apply small zigzag. Reduce upper and lower
thread tension.

© For Very elastic fabrics-

spandex (power net)

Use lapped or abutted seam.

Apply multiple zigzag.
