This design of a knotted straw rope (縄, nawa) curtain is one of Keisuke Serizawa's most famous designs and represents a unique fusion between a modernist aesthetic and a traditional imaginary, with the addition of a hint of irony, typically Japanese: the game is about camouflaging an object (the rope curtain) within another object (the cotton cloth), a game that is made even more effective and powerful when the same design is used on a noren (the typical entrance curtain of Japanese houses and shops), putting basically two curtains in one.
A timeless design, made in 1955, just before being designated National Living Treasure (人間 国宝) the following year.
Made of sturdy and thick cotton, this is a quite big (measuring 90x90cm) furoshiki, which can be also used as a small table cloth, as it can be hung on a wall.
