Yarn

Yarn is a long continuous length of interlocked fibres, used in sewing, crocheting, knitting, weaving, embroidery, ropemaking, and the production of textiles. Thread is a type of yarn intended for sewing by hand or machine. Modern manufactured sewing threads may be finished with wax or other lubricants to withstand the stresses involved in sewing. Embroidery threads are yarns specifically designed for needlework. Yarn can be made of a number of natural or synthetic materials, and comes in a variety of colors and thicknesses (referred to as "weights"). Although yarn may be dyed different colour

The name derives from Worstead (from Old English Wurðestede, "enclosure place"), a village in the English county of Norfolk. That village, together with North Walsham and Aylsham, formed a manufacturing centre for yarn and cloth in the 12th century, when pasture enclosure and liming rendered the East Anglian soil too rich for the older agrarian sheep breeds

The central bar is generally carved to make it easier to hold. Either one of the crossbars will have a flat edge to allow the skein to slide off, or will be completely removable. Niddy-noddies can be constructed of many different materials including wood, metal, and plastic. Wood is traditional, and most quality niddy-noddies are still made of wood. Budget spinners occasionally use niddy-noddies made f

In the textile arts, plying (from the French verb plier, "to fold", from the Latin verb plico, from the ancient Greek verb .) is a process of twisting one or more strings (called strands or plies) of yarn together to create a stronger yarn. Strands are twisted together in the direction opposite that in which they were spun. Plied yarns will not unravel, break, or degrade as easily as unplied yarns. When enough twist is added to the plies to counter the initial twist of each strand, the resulting yarn is "balanced", having no tendency to twist upon itself.

Woolen (American English) or woollen (Commonwealth English) is a type of yarn made from carded wool. Woolen yarn is soft, light, stretchy, and full of air. It is thus a good insulator, and makes a good knitting yarn. Woolen yarn is in contrast to worsted yarn, in which the fibers are combed to lie parallel rather than carded, producing a hard, strong yarn.
