A drop spindle is a simple tool used for spinning fibers into yarn. It consists of a shaft and a weighted whorl that helps maintain momentum as the spinner twists the fiber. The spindle is typically held in one hand while the other hand feeds the fiber, allowing the spinner to create a continuous strand of yarn. Drop spindles can be made from various materials, including wood, metal, or plastic, and come in different sizes and weights. They are often favored by hand spinners for their portability and ease of use, making them a popular choice for those interested in traditional textile arts like spinning and weaving.
