Katie Paterson's public artwork, Hollow, was unveiled in the UK in early May 2016 and is made out of 10,000 samples of different species of tree. What Do Artists Do All Day follows Katie over a ten-month period as she assembles the wood collection and creates the artwork. Sourced from all around the world, her samples include the oldest tree in the world, a tree that survived a nuclear blast and many trees that are now extinct. Katie's quest to collect tree samples takes her to an arboretum in Scotland and the national wood collection at Kew Gardens in London, to create an artwork designed to inspire wonder at the evolution of trees through time and the fragility of life on our planet.
