Janome AcuFeed Ditch Quilting Foot A useful addition to the Acufeed feet is the Ditch Quilting Foot. When you need a perfectly straight stitch in the ditch, this is the foot to choose. The guide on the foot spreads the seam allowing you to stitch perfectly in the ditch. It's perfect for quilt tops and garment construction, on waistbands, top stitching or under stitching of facings. Use with: Janome MC6600P, MC7700QCP & Elna 7300
