From Coppa Collaborative:

The Yarn Ball from Cōpp Cō. is the ideal yarn keeper.

The Yarn Ball measures approximately 6.25 inches wide by 4.75 inches high and easily holds a 100g skein of yarn and more! Two sets of holes at the rim allow you to store your needles or hooks or to thread your project. The sleek design is complimented with a deep sweeping hook to keep your yarn in place and a flat base that keeps the ball stable as you work.

The Yarn Ball is cast from durable stoneware and is available in three glazes: Bluestone, Vanilla, and Cinnamon. Handmade in upstate New York.
