I spent the better part of yesterday afternoon fighting with my Bernina 820 to FMQ. I tried a number of combinations of top thread, needles and tension. Nothing worked. It's either skipping stiches when I do a curve (going very slowly) or breaking the top thread. I finally just walked away. My LQS doesn't open until noon today but as soon as it opens I will go buy some Mettler thread and see if that works. I read somewhere (maybe on this board) that these machines are set at the factory with Mettler thread and that's all some of them like. Can anyone give me any insight on this. I've FMQ'd with this machine before. I don't know what's changed!!!
