While cleaning out my old office at work, I noticed that my co-workers were tossing out their tablets of paper because they just had a few pages left on them. I collected all of them, and removed the paper, stacked it, drilled holes in it and created this new type of journal. It is 98% reused materials.

You can also use the pasteboard back of a pad for an improvised dust pan. I’m only partly kidding. Love the look of the book.
