the bobbin tension, turn small screw (Fig. 17) on side

of the bobbin case clockwise to tighten, counterclockwise

are

properly

balanced,

a

perfect

stitch

will

be

formed

with

both

threads

interlocking

in

the center of the fabric. Fig. 18

When the upper tension is too tight, the lower thread

is pulled up over the upper thread which is lying flat

on the top of the fabric. Fig. 19

When the upper tension is too loose, the upper thread

forms

loops

over

the

lower

thread

which
