Please, please, go to daystyle.com and then her blog.(Leah Day) She has the best, most minute instructions for free motioning quilting on any machine. Sometimes the smallest things can make such a difference. I am no expert, but have been able to FMQ several quilts using her method. My largest so far was 80x80. Am just getting readyto start quilting another one. Don't give up. I use an older Pfaff, maybe 5 years old. I don't do anything with the tension. Just drop the feed dogs, don't even have to change the stitch size because I am moving the fabric.
