I recently got the opportunity to review some products from Paper Culture, an eco-friendly stationery company. The cards were elegant and fun. Check out the invites for the "Flirty Thirty" party invitations:
Paper Culture provides a mail and message program that allows customers the option of having Paper Culture stuff, address, stamp and mail the cards on their behalf, and until January 1, 2010, the only charge for this service is the actual cost of the stamps!
From their site:
◦Our paper is FSC certified as 100% post consumer recycled paper (Note: FSC trademarks © 1996 Forest Stewardship Council A.C.)
◦Our paper is Green-e certified and/or Green Seal certified
◦Generated by wind power
◦Elemental chlorine free
◦All envelopes and packaging made from recycled paper
You really should check out the modern stationery from Paper Culture - they have everything from baby announcements to birthday party invitations for kids and adults.
Here are some other great examples:
