I have tried envelopes. I have tried purse size coupon organizers. Frankly, I stink at organizing coupons. I did some research, and the The Frugal Free Gal helped me. I am now the proud owner of a coupon binder that is organized!
3 Packages of baseball card holders
3 sets of dividers
This video from the Frugal Free Gal will show you how to put your coupon binder together.
Even though they are a bit more expensive, you do need a zip-up binder. It makes a big difference, and you won't lose anything.
My daughter loves helping cut out coupons (thank goodness). My rule is that I only cut coupons that I will use. Besides the Sunday paper, there are a few other places I get coupons. About twice a month, my grocery store sends me coupons based on passed purchases. This is an easy way to save money. Target also has online coupons that you can print out. I also make sure to keep my 40% off Justice Coupons and my Kohls coupons in the zipper part of the binder.
