cabala wrote in I'm sure it's common knowledge, but...:A long time ago I tried to take the "thick" sheet protector three ring binder approach (similar to what you are referring to) but I didn't like that they sagged in the binder after adding too many modules to the binder each in their individual sheet protector. I guess the addition of a cardboard sheet might have helped but I opted for the traditional magazine bag with cardboard backer approach and store them in magazine holders on my bookshelves. I ended up liking that approach more.
