If so, Send Out Cards has the answer for you!
It’s a great service which allows you to select your card (even upload your picture to put on the card), give them a sample of your handwriting and create "personalized" cards. They even mail them for you!
The cards will include whatever message you choose in your handwriting (or a generic script, if you choose).
It’s a perfect alternative for those of you who know you should be sending stuff out, but never get around to it. You can learn more at Send Out Cards.
