Yesterday I drew an horizon. But this was a photo I took that I almost worked from. I liked the serried rows of house rooves and chimneys , but they are capped with tower blocks and modern concrete buildings up in Hanley, Stoke-on-Trent. I decided that it wasn’t what I wanted to draw. Slate rooves, old and grey, covered in lichens, no longer wrapped in the smoke of potteries and bottle ovens. Cleaner air, further views.
