At the Saint-Etienne Design Biennial in France Nendo showed their collection "colored pencil tables".
- We used a technique called 'udukuri' to carve away the soft parts of cypress boards so that the harder curves and lines of the wood grain stand out. Then we covered the boards with paper and traced the relief in colored pencils to transfer the wood grain onto the paper. This created a tantalizing juxtaposition between the familiar proportions of wooden and the finish of the paper, and an inviting fusion of the subtle shades and blur of the colored pencils with the raised wood grain.
