My newest wrist warmer pattern is called “Rainbow Love.” These are just shy of 9 inches long. The thumb hole is approximately 2 inches. By design they have a great stretch when wearing. Being reversible they will offer twice the bang for your buck, so to speak. Wrist warmers are designed to be worn on either hand. I used the Sock Loom II for this pattern, though you could use the All in One loom as they have the same gauge.
