The herder and nomadic communities used dogs and Voordho to guide and protect their  livestock of sheep and yaks. Slings are woven on small handheld looms and created in many different design patterns; the “nine eyes” one being one of the most well known. Over the centuries, the sling came to symbolize the conquering power of good over evil and even city dwellers owned slings as a sort of protective force. They were kept in a Yang-gum, an 'positive energy' box that could also contain precious stones and metals, and blessed objects. 
Made in recent years in Tibet from dyed yak hair, this one is beautifully woven to exacting standards, embellished with red tassels, and is fully functional.
