I remembered this delightful piece when me and John Constable (yes really!) started following each other on Twitter. You will have to click on this to make it big enough to read, but it's well worth it. I copied it out from a book my mum has on Suffolk during the Festival of Britain. I was doing my Art A level at the time and things like what colours painters' used was hugely important. Even now, when I go to mix a green, I still often think 'What would John do?'
