Stitches of personal choice
Reinforced straight stitch
By pressing the push-button to the right under the
arrow until the light under the symbol for reinforced
straight stitch goes on, the machine will automatically
select a suitable stitch for joining stretch fabric, for crotch
seams and sleeve insertion.
Reinforced straight stitching is preferable for sleeve
insertion and crotch seams which are subject to consider­
able strain—this applies to both stretch and non-stretch
material. Use thread of the same colour as the fabric and
baste with ordinary straight stitch.
In the majority of cases it is preferable to overcast the
edges of the fabric pieces first.
The reinforced straight stitch is also ideal for top-
stitching.
Reinforced zig-zag (Ric-Rac)
By using the same setting you can also sew reinforced
zig-zag (Ric-Rac). Set the width by pressing the 4- button
under the right digital indicator. Use presser foot B.
It is elastic like the reinforced straight stitch and is
therefore particularly suitable for sewing jersey and
other stretch fabrics.
The standard setting for the stitch length is 3.0 and it
can be increased or decreased as required.
Both these stitches can be used for topstitching. They
produce a striking effect due to the triple stitch.
The simplest way to join leather pieces is to overlap
the edges approx. 0.5 cm (3/16") and sew with Ric-Rac
from the right side. This method is also suitable when
using the patchwork technique on leather.
It is also possible to join the pieces edge to edge.
