Greenest way to make a booklet

Consider:

-wasted paper when cutting
-binding?
-use of both sides?
-use of space
-how much can you do with a piece of paper


May be I could go back to a hot dog fold....

but instead of trying to add more pages....

a hot dog fold...instead of the other side being a poster of left blank...

if you fold it the other way...you get another set of info in the other side?

1 side is tips and what people can do
and the other are facts and resources ?

At the moment it feels quite plain and the format of the booklet is quite boring...
but my concern is using as much available space as effecticely as possible....
