CHECKING TENSIONS

To check the thread tension balance, be sure to use mercerized thread of the same size on the top
and on the bobbin; and a sharp, correctly sized needle for the fabric you are sewing. Begin
with a full bobbin. Set the stitch length for about 12 stitches per inch.

Fold a 6″ square of fabric in half diagonally, forming a triangle. Make a line of stitching 1/2″
in from the fold.

a. If the seam is puckered – both tensions are too tight.

b. If the bottom thread lays on the fabric – tighten upper thread tension, and repeat test.
See Fig. 3, Page 9.

c. If the top thread lays on the fabric – loosen upper thread tension, and repeat test. See
Fig. 2, Page 9.

Grasp the stitching and pull with a snap to make the threads break.
a. If both threads break – tensions are balanced.

b. If neither thread breaks – both tensions are too loose.

c. If the upper thread breaks – loosen the top tension.

d. If lower thread breaks – tighten top tension.
Both threads do not have to break at the same place, but they should break on the same snap.

It is necessary to reduce the upper thread tension somewhat when zigzag stitching. The
wider the stitch, the less tension that is needed. This is particularly important when making
designs. It is not desirable to have any of bottom thread visible on the right side of
the fabric when making designs.
