Given no resources, the maximum height depends on my personal height and reach. No ladders, remember? I would fold a page into a V shape and place on its side. Then place a flat piece on top. I would then place a V shape on top of the flat, and repeat the process. This method would be practical considering the maximum possible heights my body could physically reach. OR… if I had access to a high area with a ledge, I would slowly fold the corners and “clip” the pages together, letting them down the ledge like a chain. This vertical alignment could metaphorically be seen as a tower. EDIT Hah…I guess if I really want to be metaphorical, I could place them on the ground, end to end. It’s not my fault you’re looking at it from the wrong axis. Better yet, I could place them in a big rectangular formation on the ground, then use the rest to add windows and doors….making a portrait of a tower.
