Straight stitching is accomplished with all
stitch levers in a downward position and with
the bight set at zero as shown in
Figs. 87 and
88 .
Central needle position is used for straight
stitching except in the unusual situation when
it is desirable to alter the location of the
needle in relationship to the center of the
presser foot.
The Straight Stitching Throat Plate
and Straight Stitching Presser Foot are
designed to accommodate all fabrics, but
especially delicate, soft fabrics, sheers, crepe
weaves and all fabrics where the weave or
finish causes the fabric to cling to the needle,
either on its upward or downward stroke.
The Straight Stitching Presser Foot is
convenient for stitching curved seams, follow­
ing the edge of a lapped seam, the fold of a
pleat or when placing an edge-stitching on a
yoke or collar. The narrow right toe affords
an excellent view at the right of the needle
for such work.
To Lock Bight Control for Straight
Stitching. When straight stitching, set nee­
dle position lever at central, bight lever T at
zero and set maximum bight stop screw X as
shown in Fig. 87. Then bring the inter­
mediate bight regulator screw U upward or
downward until you feel the notch engaged.
Test Stitch. It is a good practice to test
stitch on a scrap of fabric before stitching a
garment to determine the correctness of ten­
sions, length of stitch and pressure. The
Fabric, Thread, Needle and Stitch Length
Chart on page 16, is a useful guide to the
correct needle, thread and stitch length for a
wide variety of fabrics.
