I have the Janome 6500 that I've used for years. Can I assume that your 6700 has several different modes for different stitching? For quilting I go to Mode 2, use straight stitch #11 with the pressure foot set at 3. Using a walking foot, even a generic brand does have an advantage as it feeds the material evenly. Sure hope that someone has been able to help you out with their answers. Good luck!
