Author Kate Atherley approaches this book just like she does her sold-out classes: She breaks down complex concepts into bite-sized, approachable pieces.

No more skipping patterns because they don’t come in your exact size or settling for garments that don’t fit quite right.

With clear examples and straightforward methods, you’ll gain the skills to adapt appropriate patterns to your needs—and identify when it’s time to look for a different pattern better suited to what you want.

The best part? You only need basic arithmetic—no complex math required! Whether you’re a beginner ready to move beyond the basics or an experienced knitter wanting more control, this book will transform your crafting experience.

Through engaging storytelling, she introduces passionate farmers, innovative mill owners, and resourceful entrepreneurs already building more localized, transparent wool systems.

Whether you’re a knitter, weaver, spinner, fashion enthusiast, or simply curious about where your textiles come from, this book will forever change how you see a ball of yarn. The True Cost of Wool isn’t just about understanding a complex supply chain—it’s about reimagining a future where what we wear connects us to land, community, and a more resilient textile economy.
