Once upon a lack of technology, we wrote things down. We sent love notes, thank you cards, and (gasp!) letters. Then came texting, which drastically reduced the warmth and personal touches associated with correspondence, but also upped the eco-friendly factor. If you want to reconcile your written wants with your ardor for Mother Earth, look into U Stationery, a local stationery company priding itself on use of recycled paper and soy ink for their invitations and stationery. Plus, on Earth Day (April 22, guys), U Stationery will donate 10% of all purchases to Chicago's Gateway Green organization, a non-profit dedicated to the beautification of Chicago. So don't forget to shop for stationery this week. It might help to, you know, write it down.
