Ok, Janomes are great for FMQ. Sounds like the top tension is too loose. I used to set my 6500 to 5 or 6 (normal was 3). Also, the feed dogs should be down and it doesn't matter what stitch length you set because the length is controlled by you and how fast you are moving your quilt. I always - and I have been doing FMQ for several years - have a practice quilt sandwhich available and use it instead of my quilt until I get any issues resolved. It is also good to help get into a rhythm. Are you tensed up while trying to quilt? Try taking a deep breath and move your quilt very slowly with your machine set very slow. When you get relaxed, you can speed up with your movement as well as the machine speed. It is definitely something that gets easier with practice. Most important, don't give up! You couldn't ride a bicycle the first time you tried I bet!
