This DIY was on design*sponge not too long ago -
maybe you've seen it?

"That's the back of one of my business cards. I recycle cartons from cereal, beer, tea... whatever cardboard I can find to print my cards on! Save the planet one tree at a time!"
Carrying the recycled concept through all of your packaging
and marketing helps to reinforce the green in your work.
How do you make your business cards?
