Spun yarn is made by twisting staple fibres together to make a cohesive thread or "single."6 Twisting fibres into yarn in the process called spinning can be dated back to the Upper Paleolithic and yarn spinning was one of the very first processes to be industrialized. Spun yarns may contain a single type of fibre or be a blend of various types. Combining synthetic fibres (which can have high strength lustre and fire retardant qualities) with natural fibres (which have good water absorbency and skin comforting qualities) is very common. The most widely used blends are cotton-polyester and wool-acrylic fibre blends. Blends of different natural fibres are common too especially with more expensive fibres such as alpaca angora and cashmere.
There are several thicknesses of craft yarn also referred to as weight. This is not to be confused with the measurement and/or weight listed above. The Craft Yarn Council of America is making an effort to promote a standardized industry system for measuring this numbering the weights from (finest) to 6 (heaviest). Some of the names for the various weights of yarn from finest to thickest are called lace fingering sport double-knit (or DK) worsted aran (or heavy worsted) bulky and super-bulky. This naming convention is more descriptive than precise; fibre artists disagree about where on the continuum each lies and the precise relationships between the sizes.
Yarn is composed of twisted strands of fiber which are known as plies when grouped together.8 These strands of yarn are twisted together (plied) in the opposite direction to make a thicker yarn. Depending on the direction of this final twist the yarn will have either s‑twist (the threads appear to go "up" to the left) or z‑twist (to the right). For a single ply yarn the direction of the final twist is the same as its original twist. The twist direction of yarn can affect the final properties of the fabric and combined use of the two twist directions can nullify skewing in knitted fabric.
