Notebooks are made out of memories that ocurred during your day and night. They seem too valuable to get lost in the dustbin of your mind. Some of these elements might later on find their way into artworks or writings.
I took it the other way around...first making the artworks and much later using some of the elements to be put on my Notebook pages...which in my opinion look like artworks by itself.
With time going on these pages become more and more valuable and isn't that what souvenirs are made for?
THE BETTER YOU LOOK THE MORE YOU SEE
