Using Threads that Unwind
Quickly

I Using the Spool Net

If using transparent nylon thread, metallic thread, or
other strong thread, place the included spool net
over the spool before using it. When using these
threads, threading must be done manually.
If the spool net is too long, fold it once to match it to
the spool size before placing it over the spool.

Memo
• When threading the spool with the spool net
on, the thread may not come out enough.
Make sure that 5-6 cm (approx. 2 - 2-1/2
inches) of thread are pulled out.
• It may be necessary to adjust the thread ten-
sion when using the spool net.

I Using the Vertical Spool Pin

Use the vertical spool pin when using an irregularly
shaped thread spool, and when sewing or
embroidering with metallic thread.

Install the spool felt and the thread spool in

Memo
• When setting the thread spool, set it so that
the thread winds off from the front of the
spool.
• If using metallic thread, we recommend that
you use a 90/14 home sewing machine nee-
dle.
• This method keeps the thread from twisting
as it comes off the spool pin.
