One specific term deserves its own section: . This refers to wool that has been treated (usually with an acid bath) to strip the scales off the fiber. The thickness, twist, and fiber type dictate the

Yarn is a remarkable intersection of nature, technology, and art. From the sheep's back to high-tech manufacturing, understanding the composition and crafting of yarn allows us to better appreciate the textiles we use every day. As the industry moves toward more sustainable practices, the future of yarn looks stronger and more diverse than ever.
