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 my brother in the World Trade Center on 9/11, I picked up my knitting and discovered that what had always been a creative outlet, was also an effective tool for processing my grief. When I knit, I was able to sit still. Simple patterns provided time for my brain to rest.

It also gave me some space to think about what I wanted to do next with my life, because on September 10th, I had been laid off from my job. I wanted my work to change the world. And as I healed, I became convinced that knitting was really good for a person's mental health. (It turns out it is also good for your physical health, but those studies have only recently come to light.) So I decided to open a yarn store that would support organizations that strive to make the world a better place, and would encourage more people to knit or crochet for their own wellbeing.

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

In the 15+ years since opening, our charity initiatives have raised $40,000 for local charities. And by carefully curating products from companies that make a difference, we actively support small businesses and social justice causes worldwide. You have made this possible.
