When the upper and under tensions are properly balanced,

a perfect stitch will be formed with both threads interlocking
in fabric (Fig. 15).

When the upper tension is too tight, the lower thread is

pulled up over the upper thread which is lying flat on the
fabric (Fig. 16)

When the upper tension is too loose the up,,er thread

forms loops over the lower thread lying flat on the fabric

(hig. 17).
