We’ve got a dirty little eco-secret: we’re mad about paper. Online billing is all well and good – but from bat mitzvahs to baby showers, sometimes you just need a card. Get your notes signed, sealed and delivered the planet-friendly way with Paper Culture.

This sweet online vendor offers affordable cards, stationery, and wall art made of sustainable materials such as bamboo and paper whose post-consumer content scores top grades at 100%. The paper is chlorine free and generated by wind power, and the company plants a tree through Cards that Care  for every single order they receive.

And though they’ve got certifications coming out their ears (from the Forest Stewardship Council to the Carbon Fund), this company does not skimp on luxury. All cards are printed on 130lb heavyweight cardstock with rounded corners, professional designers work on every order, and they’ll mail your card for you for just the cost of a stamp. With February 14th not too far off, make this year’s valentine  a love letter to both your sweetheart and the planet.
