The Pfaff Sensormatic free-motion foot is used for stippling and free-motion embroidery. The foot allows for greater visibility for both stippling and free-motion embroidery. When sewing free-motion at a low speed the presser foot will raise and lower with each stitch to hold the fabric on the stitch plate while stitch is being formed. At higher speed, the presser foot floats over the fabric while sewing.
