To embrace sustainability in knitting, choose ethically sourced yarns made from natural, biodegradable fibers such as organic wool, alpaca, or linen. Opt for certified materials like Responsible Wool Standard (RWS) or OEKO-TEX® certified yarns, and support local artisans or brands committed to eco-friendly production. Thoughtful choices ensure both exquisite craftsmanship and a gentler impact on the planet.
