I started using visual diaries, journals and sketchbooks in a disciplined way in 2000, as a way to explore and record graphic ideas. There are now over 50 of them, and they are usefully shelved by date. I am constantly surprised by what they contain. They are full of things that I have forgotten, ideas that I never got around to applying, and interesting styles that I no longer use. And they are a source for new inspiration.
Here are some sample pages from recent journals. I will share more over time.
