Hi there, do you have the books that came with your machine? I have the 870 so not sure if it's the same. Today I did some FMQ... I go in spurts & starts & stops..... my settings: I dropped the feed dogs....used a 30 wt cotton thread in both top & bobbin.... selected the "C" as far as the thickness goes....changed the tools to spring foot..... also put on a single hole plate that I purchased. I have only 3 rows completed and so far the back looks not too bad. Good luck!
