Manos del Uruguary's Silk Blend is a classic and elegant yarn, featuring the unbelievable softness of extrafine merino (non-superwash), and the subtle glow of raw silk. Manos uses Tussah silk, produced by worms that feed on oak and similar tree leaves, rich in tannins that give it a beautiful golden shine. Silk Bend is a single-ply yarn that knits up clean with a wonderful stitch definition.
