Reusable coffee mug cozy Turquoise

Turquoise is the birthstone of December and while I was taking photographs of some unpolished natural rocks from my husband's rock & mineral collection I felt we just needed to knit something in this bright blue color!
Here it is, a reusable knit coffee cup cozy in turquoise color! I love these little things, they are practical, Earth friendly and works great to keep your coffee or even a hot buttered rum :) hot longer!What a great gift for the holidays!
