Spindle Whorl Process The raw fibers of plants or animal wool (called roving) are attached to the dowel, and the spindle is then made to rotate, in a clockwise or counterclockwise fashion, twisting and compressing the fibers as it collects them on top of the whorl.
What does a spindle whorl do?
Spindle whorls were used to weight spindles when hand-spinning yarn. They were made in a variety of materials including stone, ceramic fragments and fired clay.

How are spindle whorls made?
Spindle whorls are perforated weights from wooden drop spindles. Various materials were used for spindle whorls: stone (various, often local, types), shale, ceramic (baked clay, reused vessel sherds), animal skeletal material (bone, antler), wood, and lead.
What is a spindle whorl bead?
A spindle whorl is a disc or spherical object fitted onto the spindle to increase and maintain the speed of the spin. For ages the whorls have been made of many different materials: amber, antler, bone, ceramic, coral, glass, metal (iron, lead, lead alloy), and wood (oak).

How does a whorl work?
Spindle Whorl Process If the spindle is rotated clockwise, the yarn produced has a Z-shaped pattern to the twist; if rotated counterclockwise, an S-shaped pattern is created. But spinning raw fiber with a whorl produces both a consistent twist direction and a consistent yarn thickness.
What is spindle in human body?
Muscle spindles are stretch receptors within the body of a skeletal muscle that primarily detect changes in the length of the muscle. They convey length information to the central nervous system via afferent nerve fibers. This information can be processed by the brain as proprioception.
