Organic

At String Theory, "organic" is not a marketing word — it is a sourcing standard. Every yarn in this collection is certified organic, traceable from sheep or seed to skein, and chosen because the way it was grown matters. You will find GOTS-certified wool from cooperatives that pay fair wages, US-grown organic cotton from Appalachian Baby Design, and naturally dyed merino from independent makers who are quietly changing the industry.
