Paper conservation

Hi,
I would tell here about paper conservation tactics that was done by my team in Shaastra-2009.

1.)Use font size 10 always (its clear and legible)
2.)Avoid having unnecessary tab spaces and instead have a table to avoid these spaces.
3.)Try using A5 instead of A4 (a different orientation of paper will optimise the space saved).
4.)Reduce margins as much as possible.
5.)Use left over one-side printed sheets for rough use.
