Minimalist art carry = Midori travelers notebook

Since summer I have been having a love affair with my Midori Travelers notebook. Scribbling away in it, taking notes, journaling, sketching and even painting. It all fits in the books that I have bound with elastic into a sturdy leather flap. It certainly helps that the Midori paper is so great with fountain pens and even watercolor. My sketchbooks change all the time and often get left behind on busy days, but my traveler's notebook comes everywhere with me. Do you have a notebook that you carry with you everywhere? I would love to hear what other people are doing with their Midori Traveler's Notebooks and sketchbooks.
