CHECKING THREAD TENSION OF
ZIGZAG STITCHES
The easiest way to check tension is to sew a
medium zig zag stitch on the fabric you will
be using. Use the appropriate type of thread
and needie as recommended on page 17.
Sew a line of zig zag stitches. The bobbin
thread should not show on the top of the
fabric.
Adjust the top tension if necessary to achieve
the stitch indicated at left side of illustration.
OVERCASTING
This is one of the mote frequently used
zigzag
stitches
on
garment
construction.
You may want to overcast along the raw
edge of each seam allowance or fold the raw
edge toward the garment and stitch.
Stitch so the needle pierces the fabric just
short of the outside edge. Raw or worn edges
of older garments can be overcast to prevent
further raveling.
