I know this isn't a vintage machine but I have a problem. I was using a mechanic magnetic bowl to hold my pin. My mistake . I set it on top of my sewing machine. Now when I try to do fancy stitches it will only sew back wards. So that was not to bad as I don't use those stitches very often anyway. Now it has decided to sew on it own. When I turn the machine on it is okay but once I sew it does not want to stop. Does anyone have any ideas on how to fix these issues or do I have to take it to the dealer?
