Inspired by the natural simplicity of un-dyed wool and linen, Duo and Trio from Interface can be laid out in several patterns, including herringbone and linear designs. When installed in an ashlar coursing, the 25cm-by-1m plank tiles take on a seamless, broadloom-like look. Duo and Trio are made entirely from non-virgin yarn that is combined with reclaimed carpet fiber and salvaged fishing nets. interface.com
