I just got this machine and it has a great stitch. I have a question, maybe you all can help me with. I threaded the machine with Superior Invisible Thread on the top and cotton thread in the bobbin, but I can only get a little ways before it breaks. I did not have this problem with cotton thread, top and bottom. I have threaded the machine per the examples for polyester or thread that tangles or breaks (both of them) in the instruction manual, but it still only goes a little ways before the top thread breaks. Can you tell me if you have had luck with the invisible thread, and if so what settings you use? Thanks so much!
