This is a photo of all the stuff I have written and created for my RPG story world of Mist World. The world has been in development for 21 years (and the germs of it go back even farther to other settings).
These are "press board report covers" or Acco Binders [link]
I put a card stock backing on them to make them look more book like. I "laminate" them with clear packing tape (no it's not exactly high craftsmanship, but it works for me). I also use binders of course with lots of page protectors.
See my Mist World RPG folder in my gallery to find some excepts from the books. [link]
Many of my Mist World ideas can also be found in
, which a great group for Dungeon Masters and players who love dungeon crawl style RPGs.
