Make your own business cards.
This might seem like an intimidating project, but you'd be surprised how easy it is. The website Vistaprints.com has lots of good templates and really cheap prices if you're willing to have their tiny logo printed on the back. I like to use Overnightprints.com because they have a formatting program that allows you to upload your own image. If you're going out mingling and networking, having your own card is a must!
