  5. Place the spool of thread onto the spool pin.

    Slide the spool onto the pin so that the spool is horizontal and the thread unwinds to the front at the bottom.

     

    If the spool or the spool cap is not positioned correctly, the thread may become tangled around the spool pin and the needle may break.
