Wild Stuff is 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. Wild Stuff has a lot of eyelash, metallic, and other highly textured yarns. Wild Stuff has some wool, kid mohair and other animal fibers in it. Like all Stuffs, a larger needle can be used for a more open fabric in ponchos, wraps and scarves. We have successfully worked on as large as a #11 needle. Wild Stuff is interchangeable with Cool and Neat Stuff.
