Bobbin thread will appear on the top side of fabric.
C. When thread tension is decreased.
Upper thread will appear on the bottom side of
fabric.
D. Thread tension (except for straight
stitch)
Thread tension should be set to a slightly looser
tension than that for straight stitch.
The upper thread should appear slightly on the
bottom side of your fabric, for example, when doing
decorative sewing.
E. Helpful Hints
1. If your sewing appears as shown in the illustration,
stitches on top side of fabric are good but bottom
side looks very loopy, this is usually an indication
that the upper thread is not threaded correctly.
Refer to page 36 for correct threading.
2. If after checking the top thread and the bobbin
thread is still showing on the top side, check
the bobbin to see if it is set correctly. Refer to
page 34 for the correct setting.
