Silk noil, sometimes called raw silk, is a short fibre which is a by-product of combing silk before spinning. Sero is a rustic, nubby, matt yarn that weaves into an ethereal fabric with a soft hand and exquisite drape. It is an easy, consistent yarn to weave with, creating a wonderful experience for both newer and experienced weavers, on both a rigid heddle or multi-shaft looms.
