There are lots of interesting ideas out there, but I am in LOVE with Anna's products! She makes greeting cards from recycled paper and infuses them with seeds! On the front is a keepsake photograph. Plant the greeting card and in no time you'll have a living memory in the form of herbs, flowers, fruits or veggies!
I know, I know, I'm straying from my normal topic of acupuncture, here. I just couldn't resist sharing this cool, green way of saying "Thank You!" (or "My Condolences" or "Happy Birthday!" or whatever!)
