Derek Blasberg collaborated with Paperless Post to create a line of greeting cards and invitations that are witty with a hint of sarcasm. He is able to say, tastefully, what everyone else is thinking! You can send them via email, but my preferred method is snail mail (nothing beats a personalized invitation or a thank you card). The paper version is about $4.00 per single card, but drops to $1.50 if you order 10 cards or more. Browse and order some Derek Blasberg invitations from Paperless Post.
