KLASSE triple needles sew three parallel lines in one pass, creating bold decorative effects and heirloom-style stitching on compatible machines. This triple needle is size 80/12 with 3.0 mm (0.12 in) spacing between needles, which indicates the distance between points. Because triple needles are fixed in a nylon block, stitch at slower speeds and avoid prolonged continuous use to reduce stress on the needle and machine.
