A knitting needle is a long, slender tool used in the craft of knitting to create fabric from yarn. Typically made from materials like metal, plastic, or wood, knitting needles come in various sizes and lengths to accommodate different types of projects and yarn thicknesses. Knitting needles are often used in pairs, with each needle holding a portion of the stitches. The pointed end allows for easy insertion into the stitches, while the other end is usually blunt to prevent accidental pricking. Knitting needles are essential for creating items such as sweaters, scarves, and blankets.
