The blue colour and the line texture of the fabric were created by a photographic process using the light of the Sun: the fabric was treated with cyanotype chemicals while kelp and sea spaghetti blocked the light and created shadows. The initial blue colour faded and changed within days to a faint yellow as far as the sea water reached. By spanning the fabric across the cliff edge, it was exposed to natural forces — the wind and the sea played with the fabric in an ever changing way, slowly exposing different sides of its beauty.
