I’ve had the same set of watercolours in a Windsor and Newton black enamel tin since I was a first year art student at Falmouth. Over the years the pans of colours have been renewed but it’s one of those little constants I return to that makes me feel secure. I started doing quick sketches in watercolour of lockdown skies in March. I didn’t think I would need to make another sketchbook to contain them all. Yesterday it was an even pale grey all day so I didn’t bother painting it. Today it looks more interesting so I may well do several. There are no rules other than to be guided by the wind.
