This foot is most suitable to sew blindhems or to topstitch edges. The stitches only pierce the hem so that the stitch holes are hardly visible on the right side of the fabric. The blindstitch foot for Dual Feed is provided with a recess on the back side of the presser foot to activate the integrated Dual Feed. This allows an even feed of sticky materials.
