My Favorite Yarn Spinner Setup

The Horizontal Yarn Spinner paired with the Universal Yarn Clamp - hang it from your shelf for smooth, tangle-free crafting and perfect yarn flow. Keep your yarn steady and spinning cleanly. The clamp lets you hang your spinner on a shelf, desk, or table so you can crochet and knit anywhere.
