Seed Embedded Paper!
Love, love this idea from Porridge Papers and their sister company Plantable Seed Paper for letterpress paper. It actually has seeds embedded in it. I think it would be an awesome way to promote being green. Use this for an outdoor wedding invitation, baby announcement or even business cards. When the person has the information they need from the card the recycle it by planting it in the ground and it grows a variety of vegetables or flowers! You pick the seed mix you want!
