MULTI-STITCH ZIGZAG
This is a strong stitch because as its name implies, it makes
three short stitches where the normal zig-zag makes only one.
For this reason it is recommended for overcasting nearly all
types of fabrics.
It is also ideal for bartacks, mending tears, patching, sewing
towelling, patch-work and attaching flat elastic.
SETTINGS :Presser foot - General Purpose Foot
:Thread tension control - AUTO
SHELL STITCH
Turn under the raw edge and press. Place the fabric right
side up so that the zigzag part of the stitch sews just over the
folded edge, pulling the fabric in to form a shell hem. Trim
away excess fabric close to the stitching line.
SETTINGS :Presser foot - General Purpose Foot
:Thread tension control - AUTO
Helpful Hint: For a variety in appearance experiment
with different width, length and tension settings.
NOTE: Mending a tear or overedging as shown in
illustration requires manual adjustment of the length
control.
