The Janome QMP20 has an impressive 20'' throat.  The machine comes with an adjustable frame which can be set up as 4 foot, 8foot or 12foot length.  Rolling your fabrics onto the frame makes stitching your quilt less strainful on your body and allowing you to focus on your design.  The machine sits on a wheeled carriaged making it effortless to mauver it around your quilt.  Bright LED lights illuminate the throat, needle and bobbin areas.  These lights can also be adjusted to suit your own eye sight.  Stitch regulation helps the quilter to create even stitches and there are two modes to choose from cruise and precision.  Manual mode is another option and this is great for applications like micro stippling.
