Converter
A
serging
seam
is
generally
sewn
with
3
threads.

the
converter
you
can
dispense
with
one
thread
i.e.
you
just
continue
to
sew
with
2
threads
and
thus
save
a
lot
of
thread.
Wherever
a
2
thread
seam
is
enough
i.e.
for
elastic
materials
and
materials
that
hardly
fray,
you
can
still
make
neat
edges
with
less
thread.
You
can
also
make
very
effective
fancy
seams
with
the
converter
using
mercerized
cotton.

seams
