From the Norwegian word for happiness, Lykke crafts their Driftwood Interchangeable Set using lightweight laminated birch made to resemble driftwood … Happy-making, indeed! This 5-inch Set has the needle sizes and cords lengths typically used for sweaters, scarves, and blankets, including 12 tips, each measuring 5 inches from tip to connection point, in a size range from US 4 (3.5 mm) to US 17 (12 mm). Housed in a gray denim or black faux leather case, you’ll also find five cords (two 24-inch, two 32-inch and one 40-inch), as well as two connectors, eight stoppers, and four connecting keys. Each tip is stamped with both the US and metric sizes for easy identification, and changing tips is a simple twist on the cord with a key. All the needles you need for so many of the things you want to knit… And beautiful, too! Prefer 3½-inch tips? Check out Lykke's 3½-Inch Driftwood Interchangeable Set!
