Gerald Scarfe - "The most important thing is to build up a mood, which is productive in liberating your imagination further. I fully believe in 'attacking' the paper so that you can bring out what you are visualising in your mind. i liken it to a dream - even as you are recalling it and attempting to tell someone about it, it starts to evaporate - and you cannot remember the end, so getting the 'bare bones' down is crucial. Even three or four lines can work as a stimulus to develop the piece. Sometimes i am knee deep in paper bring to work an idea through, but it comes eventually."
