Bernina Large Spool Disk

This Bernina spool retaining disc slides onto your horizontal Bernina spool peg and holds the thread in place. We recommend that you slide the spool retaining disc on and leave a very small gap between the thread and the disc. 

Always also remember that if your reel of thread has a nick, or 'grip' to hold the thread, it must be placed away from the retaining disc. This will prevent thread catching as it peels off.
