This bold hand knotted pile rug is made with handspun wool and bamboo silk highlights. The radiant accent colors in this rug are all bamboo silk. Bamboo silk fiber has a natural sheen and softness that feels and looks like silk and yet is more durable and easier to clean. And bamboo is one of the most sustainable natural resources known. The rich variegated brown and grey tones of the background colors are entirely handspun wool in natural un-dyed natural wool. Thick and warm and glorious and decidedly modern; the classic and timeless motifs of a Persian Isfahan carpet is updated in new colors and textures in this remarkably beautiful piece.
