Clover's darning needles with a handy latch hook allows easy threading of multi-ply and bulky yarns, including those frustrating fraying yarns. Just a case of opening up the latch, slipping the yarn in place and closing. Nice and easy, and just what I like. Clover darning needles are great whether you're sewing up your latest work, or you're repairing it. They're super helpful to have close at hand.
