The spinner spins the weighted spindle pulling off a mass of fibers which is twisted into yarn.
Historically, whorls have been made of materials like amber, antler, bone, ceramic, coral, glass, stone, metal (iron, lead, lead alloy), and wood (oak).
Local sourced materials have been also used, such as chalk, limestone, mudstone, sandstone, slate, lydite and soapstone.
Natufian artifacts unearthed in Israel at Nahal Ein Gev II, an archeological site, are believed to be the oldest spindle whorls found to date.
Archaeologists say the perforated pebbles found scattered at the village site are 12,000 years old.
