One of my obsessions – notebooks

I have a few obsessions (rangefinders, Tri-x film, fountain pens, steel-framed bikes, and more…). One of them is notebooks. I’m not hard-wired to be organized, but I have been into GTD for years and over time have modified it to suit my needs. I love Moleskine notebooks and use several variations. Awhile back I ran across a post about the Dot Grid Book from Behance and I ordered one. I like the heavy paper and the subdued dot grid. It is great for taking notes and the subtle grid provides a ready canvas for your sketches, process diagrams or book layouts. I just ordered two more and they came in the mail yesterday. What are your favorite note taking tools?
