UPPER THREADING—TWIN NEEDLES
Place a spool on each of the two spool pins.
Thread each point with one thread at a time in the same
manner as for single needle threading with exception of the
tension.
Pass one thread between the rear and center
tension discs and the second thread between the
center and front tension discs.
Thread the eye of each needle from
front to back. Threads must not cross
or bind each other.
<
Start to sew with threads positioned in
the same way as when stitching with
single needle.
