I take A4 paper from the printer, cut it in half (making A5), and clip it together with a large bull-clip at the top left. Discard pieces of paper when done, or file them (or scan/photo) when need to retain. Can discard in groups, creating small folders, clipped together with other bull-clips. A never-ending, revolving notebook.
