Sock yarn is a type of yarn specifically designed for knitting or crocheting socks. It is typically made from a blend of materials, such as wool, nylon, and sometimes acrylic, which provides durability and stretch. The wool content offers warmth, while the nylon adds strength, making the finished socks long-lasting and comfortable. Sock yarn usually comes in a variety of colors and patterns, allowing for creative designs. It is often lightweight and has a fine gauge, making it suitable for intricate stitch patterns. Many crafters enjoy using sock yarn for other projects as well, such as shawls or baby items.
