I don't (as a rule) sew over pins. Bernina's don't like them and I accommodate my machine. It is far too much money to service a bernina once a year much less have an extra cost for timing troubles. Bless your heart, this was an expensive learning experience. They are increasing the cost of the servicing around here by a lot. Where it used to be a hundred dollars it is now a hundred and a quarter. Is it that way there too?
