I saw the coolest tutorial that a lady on Beate's Yahoo group found, and I had to try it. It's an all-in-one stationery box that includes cards, tags, mini cards (or love notes), a place for stamps, and a pen. Instead of an address book, I added post-it notes for reminders. I didn't get to make the cards yet, but I was so excited about the container that I had to share!
Here's the tutorial - I think you should try one. :)
