The idea for the [[Spinning Jenny#Origin and myth|spinning jenny]] is said to have come when a one-thread spinning wheel was overturned on the floor, and Hargreaves saw both the wheel and the [[spindle (textiles)|spindle]] continuing to revolve. He realized that if several spindles were placed upright and side by side, several [[Yarn|threads]] might be spun at once. The spinning jenny was confined to producing cotton weft threads and was unable to produce yarn of sufficient quality for the warp. A high-quality warp was later supplied by [[Richard Arkwright|Arkwright's]] [[Water frame|spinning frame]].

Hargreaves built a jenny for himself and sold several of them to his neighbours.{{sfnp|Baines|1835|p=162}}
His invention was initially welcomed by other hand spinners until they saw a fall in the price of yarn.

Opposition to the machine caused Hargreaves to leave for [[Nottingham]], where the cotton [[hosiery]] industry benefited from the increased provision of suitable yarn. In Nottingham Hargreaves made jennies for a man named Shipley, and on 12 June 1770, he was granted a patent, which provided the basis for legal action (later withdrawn) against the Lancashire manufacturers who had begun using it. With a partner, Thomas James, Hargreaves ran a small mill in [[Hockley, Nottingham|Hockley]] and lived in an adjacent house. The business was carried on until he died in 1778 when his wife received a payment of £400.{{sfnp|Baines|1835|p=162}}
