This is how I lay out for a new 32 page PB idea. I number the pages, mark off title page(s) and scribble notes and crude sketch ideas all over these Post-it Notes. If something's not working, rrrrip off that Post-it and put down a clean one! Replace, move them around, no big investment in any set ideas at this point. It helps enormously in getting the rythym of the story sorted out before I invest real time in more developed writing and sketches.
