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 needle 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 more 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,
