Composed of 30-40 different hand dyed, gauge coordinated yarns. They are tied together end to end by hand, so that as you knit the texture and colors are always changing. Moderate eyelash, metallic, and other highly textured yarns. Cool StuffTM has no wool, mohair or other animal fibers in it.
Prism offers this yarn in two sizes - a half skein is 150 yards, but a full skein is actually 300 yards.
