90% of my quilting is straight line. I mark the quilt with my six foot or four foot straight line 2 1/2" ruler. I can follow the marking line with walking foot pretty fast. I do cross hatching with squares or diamonds any size straight set or on point. For all over loopy quilting I just wiggle the quilt under the walking foot following the marking line as a reference. I won several viewer's choice for machine quilting at local shows. I can quilt a queen size quilt in less then six hours.
