About our Yarns

Our collection is first and foremost, conscientiously-curated. On our (physical and virtual shelves), you’ll find a wide selection of organic, fair trade and artisan yarns, each a delight for knitting and crochet.

By purchasing a yarn from String Theory, you’re lifting up a number of small and female-owned businesses. We help women in Rwanda, who survived the genocide, educate a new generation. We help women in Uruguay find meaningful work without leaving their rural homes. We help a family in New Hampshire maintain a mill, a tradition spanning hundreds of years. We help restore the Patagonia Grasslands by encouraging sustainable farming. Every yarn we stock makes a positive impact.

How String Theory Began

After the death of her brother in the World Trade Center on 9/11, Janet instinctually turned to her hobby of knitting as a way of working through her grief. Through this daily practice of handiwork, she found much-needed solace, easing the difficulties of such a painful time.

Having been just laid off from her job on the 10th, Janet grappled not only with her sadness but also yearned for a renewed sense of purpose. Her love of craft, her desire to make the world a better place and a yearning for community combined to become String Theory.

“Every time you spend money, you're casting a vote for the kind of world you want.”
- Anna Lappe

String Theory’s central mission is to encourage the crafts of knitting and crochet so that each person can reap the health and mental benefits, as well as promoting products from companies that make a positive impact in the world.

In the 15+ years since opening, String Theory has realized this mission. Its charity initiatives have raised $40,000 for local charities. And by carefully curating products from companies that make a difference, the shop actively supports small businesses and social justice causes worldwide.
