An indigo saffron Yak Soo weave rug. This Sprouts Indigo Saffron rug is one of our most natural and organic designs, made from 100% wool and dyed with vegetable based dyes. This design is constructed using our Tibetan Yak Soo weave which is about one inch thick, our thickest construction. The color in Sprouts Indigo Saffron has multiple layers with blue and yellow dyes that create a green carpet with remnants of the saffron yellow and indigo blue. The color combination and variations in the dyed yarn create a natural striation pattern throughout the rug.
