Independent yarn shop in Glen Ellyn, Chicago suburbs — and online. Knitting & crochet classes too. Every stitch connects.

Natural-fiber yarn from women-led cooperatives, Black-owned studios, and indie dyers in organic and fair trade fiber. String Theory is a feel good yarn shop in the western suburbs of Chicago. At String Theory we feature yarn from companies that are environmentally friendly and socially responsible: Manos del Uruguay, Blue Sky Alpaca, Woolfolk, Handspun Hope, Appalachian Baby Cotton and more. We love color, so at any time you might find Malabrigo, Madelinetosh, Knitted Wit, Dream in Color, and our exclusive Migration Yarn - but they arrive when they want to and disappear quickly.
