Copenhagen-based graphic designer and illustrator Petra Kostova of Pet & Dot creates dazzling galaxies composed of millions of stippled dots. To produce her concentrated star systems and cloudy nebulas she uses technical pens (either rOtring Rapidograph or Isograph) to draw on black and white paper. Due to the limitations of her color scheme, each work is completely formed through the intensity of her chosen dots—a meditative process which can often take her several weeks or months to complete.
Kostova also produces handmade prints created by a technique called Photogravure, which accurately reproduces her stippled detail. You can find these, and her original drawings, on her website and Instagram.
