Diptych by Lex PottDutch designer Lex Pott used a single Douglas fir tree to create her Diptych series of furniture that highlights natural wood grain. The tree was planted in the 1960s and harvested in 2013. Pott covered some portions of the milled planks with rubber, then sandblasted the boards to remove the softer wood to create spaces between the rings. "You can see the life of the tree in the wood: good summers give a wide annual ring, harsh winters a thin one. By sandblasting you blow away the soft rings of summer, leaving a gap," she states on her site.
