A site that lets you create your own personalized gift book (or cards, or booklets, etc.) full of stories or memorable moments about your special someone or yourselves as a couple. I've seen similar books before, but this one left me literally lost for words (okay, it didn't, but I had to use that line). Anyhow, if the budget allows, they make great favors. If it doesn't, purchase one and use it as a guest book.
