I don’t know if this qualifies as an “Addict of the Week” post, but here’s some thoughts on notebook use from Surviving in Argentina:

The one with the wire coil is my old notebook, the one I used last year and was mostly dedicated to help with my book. I carried it around all day and made small notes of what I wanted to write down later that day, or ideas I thought I’d be missing form a certain chapter.
I found this to be incredibly useful. It also worked for everyday work such as writing down measures, making floor plan sketches, even writing down improvised signed receipts so as to keep track of work begin done and money paid.
The notebook ended up pretty messy, yet functional: If I wrote something down somewhere else I just glued it to one of the notebooks pages, if I need more space I’d use another larger page, fold it and glued it too. If I needed more space to continue a line of thought wrote somewhere, I just cut a couple more pages with my pocket knife and glued it where it was needed….

The other notebooks are a Moleskine, and a hand-made watercolor notebook.
