Green tip: The Greenest of Greetings for St Patricks Day

There's nothing quite so green as sending green St. Patricks day cards from a site that supports greening... is there?  Of course, sending green Easter Cards isn't a bad idea either... but why stop there when you can send all of your birthday cards in a green way too?

Unless you send tons and tons o' cards every year, this probably isn't going to stop global warming. But, every bit helps, so why not?
