Double-pointed needles are a type of knitting needle that have a pointed tip on both ends. They are typically used for knitting in the round, especially for smaller projects like socks, sleeves, or hats. This design allows knitters to work with multiple stitches at once, making it easier to create circular shapes. These needles come in various sizes and materials, including metal, wood, and plastic. Knitters often use a set of three or four needles, with one needle serving as the working needle to create stitches. Double-pointed needles are essential tools for many knitting enthusiasts.
