I LOVE Binders

I have this obsession with binders.  It's probably because I really don't like filing, I like being able to just close a book and stick it on a shelf.  My issue was that I had so many binders with different purposes, that it got a little overwhelming. 

Now you probably already do this, and I was just late to the party, but this year for those binders that only had one purpose and weren't full, I decided to make flip binders.  Flip as in one direction it goes one way...

(looks totally normal right?)

But inside it's actually upside down - the only thing upside down is the pocket, but it still holds material in it.   

The "correct" side of the binder is flipped around - so I get 2 uses out of each binder that I use on a daily/weekly basis.  No use wasting binders when I can fit 2 pieces of curriculum in it.  

See - totally normal inside.

Here's another flip binder that I use a lot.  ELA answer keys are going in one direction...

Math are on the other side.  This way I don't have to always flip past the ELA to get to the Math, it's just a matter of flipping the binder. 

Do you do this too?  Am I just weird?
