Lil Sister Kits Blocking Wires are a fantastic tool to help you shape your knit and crochet garments. The titanium wires are extremely flexible and will curve along with your lace edges. They will not rust or corrode, and will return to their original shape after use. The handy zippered pouch contains three 55-inch, 32-inch and 24-inch wires and t-pins. Because of the compact size, this will store easily and will slip into your Cocoknits Block Set bag!
