DMC darning needles are long hand needles for mending and reinforcing garments, socks, and other textiles where you need to span stitches and reach through layers. This pack provides single size 18: 6 needles in size 18, with needles measuring about 2–2½ in (51–64 mm) long. Match needle size to your repair thread, and keep needles clean and dry between uses so they stay smooth for repeated repairs.
