So the day's finally come when I have to translate all those Sobell sketches into one drawing.
It's time to put something down on paper.
Trouble is, the paper's about 5 x 12 metres.
And it's glass.
I spent the first day sketching out in chinagraph.
What you can see in the background is the Wellcome's very fine Peyton and Byrne cafe.
You can see me drawing live at the Wellcome Collection this Wednesday and Friday.
