String Theory Yarn Co

String Theory Yarn Co Eco-friendly and socially responsible yarns and supplies for avid knitters and crocheters. Shop in-store or online. We love beginners!

We are located in Glen Ellyn IL, less than one block north of the Glen Ellyn Metra station. 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 y

ou might find Malabrigo, Madelinetosh, Knitted Wit, Dream in Color, and our exclusive Migration Yarn - but they arrive when they want to and disappear quickly.
