At one time, I also found my fmq was better with the feed dogs up. Now I still don't lower them, I just set my stitch length to zero, so while they are up, the do not move. But I have done it all three ways (feed dogs up and moving, feed dogs lowered and feed dogs up but not moving) with good results all around. Just find what works for you (and your machine) and go have some fmq'ing fun!
