Yesterday, I had a look at the Subway Sketchbook – in short a graffiti doodle notebook. I was disappointed. A much more exciting alternative is the Walls Notebook from Quirk Books which is much more inspirational doodlebook.
It is available in the UK at Amazon, Urban Outfitters and a range of crafty/gift stores. Just look at examples of lovely work using the notebook.
It just makes me want to get stuck right in.
