I free motion quilt with my Kenmore. Tape a thin sheet of plastic, like template plastic over the feed dogs if they don't drop, then loosen the pressure on the presser foot--the knob at the top turns to tighten or loosen pressure. Lower the presser foot and it should allow the fabric to move without tugging hard, but still provide a little tension. Run the machine a bit on the fast side as you move the quilt around. (Try this with a sample piece of sandwiched fabric and batting to practice. You may have to adjust the tension a little bit.)
