is dependent
on
the
correct
relationship
between needle,
thread
and
fabric.
Select
the
proper
thread
sizes
and
needles
from
this chart.
The
same
size
threads
should
be
used

an
the
bdbbin.
Some
experienced seamstresses
prefer
a
somewhat
thinner bobbin

the
bobbin
thread
never
should
be
thicker
than
the
needle
thread.
For
embroidery
and
