I started this project with a few rules to guide me - each print would be A5, and contain the date of the journey, the time i got on the bus and some indication of the length of the journey, images documenting the trip, and the number of the bus.
Pretty soon those rules got abandoned, as i forgot to look at my watch, or write things down, or wanted to do things a different size, or ran out of A5 lino.
i didn't mind though, those rules helped me to get started on the project and gave me some sort of framework for thinking about it, but it soon expanded beyond them.
in the end i sort of agree with the art school graffiti- writer. When it comes to art, any rules that do exist are only there for you to flex against, play with and wilfully disregard if you want to. that's part of the fun of it...
