The Open-Toe Free-Motion Spring Foot is excellent for free-motion sewing and quilting. This foot is open in the front for optimum visibility while stitching. The spring action keeps the fabric from lifting with the needle as the stitch is being formed. The fabric is guided manually when free motion sewing or quilting. - See more at: http://www.pfaff.com/en-US/Accessories/Open-Toe-Free-Motion-Spring-Foot#sthash.qCif9qkw.dpuf
