I've changed the needle twice, changed bobbins, rethreaded the machine, taken the foot off, put it back on just to make certain everything was where it needed to be and then had 2 chocolate chip cookes. LOL!! I've ordered a new foot so I'll just wait until it gets here and if that doesn't make a difference then I guess I'll have to find a repairman. In the meantime think I'll have another chocolate chip cookie. ;-)
