I made these binder covers because I binder file. Instead of using a filing cabinets with file folders, I buy the 3 inch binders and a BUNCH of sheet protectors. I have a sheet protector for each "theme". For example, in my Science binder I have a sheet protector that holds all my originals for our plant unit, animal group unit, habitat unit, etc. It takes a lot of work to start, but I promise it is well worth it in the end! A lot easier to go through and pull a unit. And your originals stay nice and neat! I also print labels and stick those on the top right hand corner of each sheet protector for a name tag.
