Blindstitch Foot number 5 for invisible-hemming. When you sew a blind-hem with this foot, the stitching can scarcely be seen on the good side. With Bernina Blindstitch Foot the stitch is formed over a special blade that acts as a guide, creating a slightly loose stitch so that the hem lies nice and flat. When the fabric is pressed flat, the needle-penetration points on the front of the fabric “close up”, making the seam virtually invisible. What’s more, the guide blade ensures an even distance to the folded edge, allowing the hem to be sewn neatly and consistently. This foot can also be used for narrow-edge stitching medium weight and thick fabrics with the needle position to the left or right.
