Merino wool / Superwash Merino Wool / Silk - Fiber Optic Yarns

40% Merino wool, 40% Superwash merino wool, 20% Silk.  Regular merino wool and superwash merino wool take dye differently, with the superwash merino wool taking the dye more intensely of the two.  The combination of both regular and superwash merino wool along with silk creates a complex canvas for the dye to strike.
