Hand spinning on these types of wheels, both hands are free (since the wheel is turned with a treadle, rather than by hand), so the spinner can use one hand to draft the fibres and the other to wet them. Modern powered spinning, originally done by water or steam power but now done by electricity, is vastly faster than hand-spinning. The spinning jenny, a multi-spool spinning wheel invented c. 1764 by James Hargreaves, dramatically reduced the amount of work needed to produce yarn of high consistency, with a single worker able to work eight or more spools at once. At roughly the
Spinning wheel then wound onto the spindle by moving it so as to form a right angle with the spindle. This type of wheel, while known in Europe by the 14th century, was not in general use until later. The construction of the Great Wheel made it very good at creating long drawn soft fuzzy wools, but very difficult to create the strong smooth yarns needed to create warp for weaving. Spinning wheels ultimately did not develop the capability to spin a variety of yarns until the beginning of the 19th century and the mechanization of spinning. In general, the spinning technology
