THOREAU offers the fine hand and bloom of Yak fiber, along with the strength and luster of Mulberry Silk. This base blooms to create a clean full stitch definition while retaining a clean diameter around the yarn (minimizing halo). Unlike many yarns with such a deliciously soft hand, Thoreau achieves a superb stitch definition which accommodates lace as beautifully as stockinette. This base offers lightweight warmth in the coldest Winter months, and at a more open gauge it is a perfect choice for an airy wrap in the Fall and Spring seasons.
