Hand knotted by HRI in India. A very dense pile of PET yarn that is not only long wearing but also stain resistant, great for high traffic areas.This is definitely a Performance area rug. The unique design has the look of 'crackle glass' in colorations that range from white on white to rich charcoal and grey. Crackle glass was first introduced in Venice in the 16th century and is as popular as ever in today's contemporary home furnishings.
