This is a positively scrumptious yarn blend of superwash merino, with a bit of luxurious cashmere and some nylon for strength. It is soooo ultra-soft and lofty, great for socks or any next-to-the-skin garment. Hand-dyed in many unique colorways using professional low-environmental-impact acid dyes. While it is superwash and may be gently machine washed, your garment will last longer if it is hand-washed and dried flat.
