The same round holes, located in,seemingly random, reminiscent of something in between the blocks of the game Tetris and the characters in the movie "The Matrix." Scandinavian designer Ida Thonsgaard has created such original perforated curtains tailored to order for a single house in Germany. The main idea was to create an illusory picture that comes to life only when the light penetrates the dense curtain and fills the room with the shimmering glow of pearls. Perforation on the curtain canvas is made bylaser equipment. In the same way, you can apply any abstract ornament, pattern or image to the fabric, for example, the recognizable silhouette of a night city with skyscrapers or a starry sky with all the constellations we have known since childhood. Such a modern design of curtains in the spirit of digital technology will give a stylish look to any interior. Perforated curtains can be hung either in living rooms, or in offices, public institutions or on verandas, terraces. Can I somehow create such a perforation with my own hands without a laser, at home? Theoretically it is possible, but this process will be long and time-consuming. The technique is called guilloche or tissue burning, a special device is used, similar to a soldering iron - a burnout! Heated to a high temperature needle cuts a hole in the canvas, immediately burning edges. By the way, if there is no burner, then you can try an ordinary thin soldering iron. The material also matters - the artificial canvas is more convenient to burn. In this version, a dense blackfabric, but if we take a lighter matter with perforations, then it will get rid of the blinding sunlight, making it scattered, and the effect of the dot pattern will remain. If, at night, the light of lanterns or the Moon, penetrating through perforations, interferes with sleeping, then a second curtain of dense fabric can be used.
