New Year, New Budget

We have decided to make a budget and actually stick to it this year.  We've been known to make them before, but terrible to stick to it.  One think I need to learn to do is to coupon.  I have the general idea and I've watched a ton of tutorials, but I need some advice on organizing them.  There are so many organization methods out there, but I want to know which one is most practical.  Those of you who coupon, how do you keep them organized and where did you get your supplies?
