behind the presser bar.

ADJUSTING THREAD TENSION

Test stitch performance on a scrap
of material you are going to use.
With correct tension { @), upper
and lower threads tension is equal
and strong enough to lock both
threads in center.
If upper tension is too tight (loose),
upper (lower) thread lies straight
along upper (lower) surface of fabric

( ®' © )■ Correct by turning

tant to follow the instructions

carefully.

Make sure that the sewing is set
flat. Needle must be perpendicular
to the seam so that it penetrates

the cloth properly.

Improper setting causes deflection

and possible breaking of the nee
dle. For sewing of very thick cloth,
sew gently, maintaining the cloth

perfectly by hand.
Breaking a needle is not a mechan

ical problem, but simply misuse.

DOUBLE PRESSER FOOT LIFTER

or two threads of fold.

(D Correct seam.

(D Needle is catching edge of fold

too much.

© Needle is not catching edge of

fold at all.

OVERCASTING

For light weight material:
Set machine on zig zag as shown
Overcasting prevents edge of fabric
from fraying and produces neat
finish.

Place the seam allowance under
the presser foot with the edge of
the seam in line with the side of
the presser foot as illustrated.
Trim the fabric to the stitch line.

-22-

For thick and elastic, and also
very fine material:

Set machine on tricot stitch as shown

the button in between the buttonhole

holder and stopper, and fully tighten
by fixing the screw. Remove the
button.

ATTACH BUTTONHOLE FOOT

Draw up the lower thread.

Pull the thread of the needle thread through

the needle hole of the buttonhole foot, attach

the buttonhole foot and draw both needle

thread and lower thread to the left. Insert the

fabric under the foot, and lower the needle

at the starting point.

Than lower the buttonhole foot.

HEIRLOOM STITCHES

Set machine as shown.
These are versatile stitches

for decoration and
embroidery.

1. Always make a practice design on a scrap
of the fabric you plan to use.

2. Start with a full bobbin and plenty of thread

on the spool to avoid running out of thread
in the middle of your design.

3. Reduce the top thread tension slightly.

4. On a very soft fabric you may want to use
a tissue paper backing or organdy that can

be cut away afterwards.

-28-

FEATHER STITCH

Set machine as shown.

Use the Feather Stitch as a decorative
top stitch or when hemming blankets,
tablecloths or draperies or when
embroidering.

1. Place the fabric right side up and sew 1 cm (3/8“)
from the edge of the fabric.

2. Trim close to the stitching.
The stitch will prevent the fabric from unravelling.
