Blue Green Lush Silk Pocket Square


Blue Green Lush Silk Pocket Square is backordered and will ship as soon as it is back in stock.

This pocket square is super cool and beautiful. We used microscopy images of cyanobacteria cultures from samples taken in the Byers Peninsula, Antarctica. We created a silk square that shows the intricate patterns of cyanobacteria cultures with its unicellular and filamentous species cohabiting. During the Precambrian, around 2.4 billion years ago, tiny microbial organisms called cyanobacteria or blue-green algae instigated the greatest change in the earth’s atmosphere so far – biological production of oxygen by photosynthesis. This oxygenated our planet, paving the path for more complex lifeforms to emerge including us humans. Through our design process, we manipulated the colours and the shapes of these intricate cultures and created a pattern that shows their characteristics but also added new shapes and a twist to it. Inspired by computer circuits, how cities and society are built and how we are all interconnected with each other, this design takes us on a journey of discovery. Find the glowing cells, circuit like shapes or ancient Mayan forms hidden in the pattern.
