Re: Bobbin jumping around during embroidery

Most of the time a jumping bobbin is due to there being a burr on the bobbin itself or somewhere on the bobbin case or hook race of the machine. It can also happen if the bobbin is the wrong size, e.g. a Singer class 66 bobbin. That's probably not the case this time though. I would wind a new bobbin. If it still jumps then look at the bobbin case and hook race under bright light and magnification.
