I really like quickly flipping through my sketchnotes as a way to refresh my memory. I thought I’d collect them into a PDF to make it easier for people to learn more and remember. I labeled all the sketches and made a manually-hyperlinked table of contents to make it easier for you to browse. =)
As an experiment, I’m sharing it as free / pay what you can. See Sketchnotes 2012 by Sacha Chua for details!
