AUTOMATIC BLIND STITCH HEMMING
(MODELS 236 & 236BH only)
Blind Stitch Hems provide a durable
hem finish that is almost invisible and comparable with
Hand Sewing.
The main 'secret' in producing a Blind Hem
is in the folding of the material, by following these instructions
and
diagrams
carefully you should encounter no difficulty,
If in any doubt, practice the 'folding' with
a piece of
paper or spare fabric. Work with the 'wrong side' of the Material
uppermost and allow at least 21%"
*
in excessof
your final
desired length
It is also
advisable
to choose a
closely matching
coloured
thread.

STEP 1. If you have material with a 'raw edge' first turn up simple hem approximately 3/8" deep and baste in
position.
STEP 2. Now turn up Material to final desired
hem length and press into place.
STEP 3. This is most important.
With 'wrong side' still uppermost open out again and bring
over remainder of
cloth to form another fold on top of (see diagram) but approximately
1/4" short of your first fold
made in Step 1,
STEP 4. With the Material thus
arranged place under the Presser Foot and proceed to sew as diagram. The special
device in the Machine will 'throw' one stitch at intervals and the Material must
be positioned so that this
stitch just
oenetrates the fold, The freouencv of the 'throw' can be altered by adjusting the Stitch
length
lever. This may
be necessary according to the type or thickness of fabric.
STEP 5. When complete unfold Material and press flat. Stitches should then
be practically invisible.
