The vertical spring action of BERNINA Darning foot #9 prevents the fabric from flagging and produces a neat stitch pattern. This foot is also suitable for free-motion embroidery. Ideally suited for free-motion embroidery and contour quilting; producing attractive lace and monograms. Its special shape makes it very versatile; repairing holes and tears using the hosiery darning hoop. For 5.5 mm and 9 mm machines.
