80% superwash merino wool and 20% nylon super fluffy pencil roving! This roving is unbelievably soft and very smooth, and since it is pencil roving, there is no need to draft - simply enjoy your spinning and watching the colors meld. It has a little very fine nylon blended into it to help it wear well, but it is difficult if not impossible to feel the nylon - not even remotely scratchy or stiff. You get the benefit of tough as nails hard-wearing yarn after all your hard work AND the extra-plush ultrasmooth butter softness of beautiful merino yarn to knit (and wear). The pencil roving comes in a generous 4 ounce lots. Espresso, coffee, mocha, and hot chocolates.
