The Free Motion Ruler Foot allows you to create a beautiful style of free motion quilting in conjunction with your ruler templates.  The perfectly circular shape allows you to sew a constant ¼” away from the edges of your ruler template.  Red markings on the foot indicate the center of the foot, making it easy to line the foot and the ruler up when sewing.  Cutouts in the front and side of the foot make it easier to see right up to the needle.
