In Autumn 2020 Paul was commissioned to design a window installation for Battersea Park Library, as part of Nine Elms Arts Ministry 2020 advent calendar project, on the theme of ‘Light in the Darkness’.

The design is based on illustrations from the book ‘Spinach at Christmas’ and carries the caption ‘Spinach thought of all the times that day that light shone in the darkness… and how wonderful it was!’ The window was opened by the Mayor of Wandsworth, Councillor Jane Cooper, on 04 December 2020.
