The class will be good for you. My dealer charges $110 to maintain my Featherweight. They have a tendency to freeze up. Will you ask the teacher "Why" they do that if you take the class? My featherweight sewed wonderfully and then for no 'visual' reason, froze. I can't afford to take it in to the repair shop, everytime this happens. (I would take a class if my dealer offered it).Thanks. Eiltcoq.
