tencel

http://www.sanguinegryphon.com/

2oz tencel (lyocell) in a long, narrow roving, incredibly shiny. Tencel is made from processed wood pulp and, while it's too slick to spin by itself, it is often blended with other fibers, especially wool, to add shine. Try it in a 50/50 blend with merino for a delightful effect.

Note: tencel fibers tend to stick together and are difficult to blend on a coarse toothed carder, but easy enough on finer cloth models.
