This foot provides superior visibility and is great for curves and precise topstitching. It holds fabrics firmly in sync with the feed dogs to achieve professional results. For use in combination with the Professional Grade Needle Plate (HP). Great for curves and precise topstitching due to the narrow foot width with superior visibility provided by the shape of the slit at the front of the foot. Provides smooth feeding of top layer of fabric in sync with bottom layer for quilting and sewing leather or vinyl. Matching the edge of the fabric against the edge of the foot will give you a perfect 1/4" seam allowance. Use with: Only Continental M7, fully upgraded  Horizon MC15000, MC15000V3, MC6700P, fully upgraded MC9400QCP, MC9450QCP, this foot ALSO works on the Janome Skyline S9-Indigo version. This machine has a darker indigo blue accent color than version 1 which had light blue accents.
