毛線球, or "yarn ball," is a round object made from strands of yarn that are wound together. It is commonly used in knitting and crocheting, providing a convenient way to store and use yarn. The ball shape helps prevent tangling and makes it easy to pull the yarn as needed. These yarn balls come in various sizes and colors, catering to different crafting projects. They can be made from different materials, such as wool, cotton, or synthetic fibers. Many crafters enjoy using 毛線球 to create items like scarves, hats, and blankets, showcasing their creativity and skill.
