Humanity’s relationship with yarn predates written history. The earliest known fragments of yarn date back to the Paleolithic era, roughly 20,000 years ago. Early spinners used simple drop spindles to twist plant fibers like flax and nettle. The invention of the spinning wheel in India between 500 and 1000 AD revolutionized production, transforming yarn from a precious commodity into a trade good. The Industrial Revolution’s spinning jenny and water frame turned yarn into mass-produced merchandise, making knitting and weaving accessible to the middle class. Today, while machines produce most yarn, a renaissance in hand-spinning celebrates the artisanal quality of small-batch fibers.

While both use yarn, knitting and crocheting produce radically different results.
