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 fiat on the fabric (Fig. 16).
When the upper tension is too loose, the upper
thread forms loops over the lower thread lying flat on
the fabric (Fig. 17).
