Self-promotion

Having to write your contact details on a Post-It note can look a bit unprofessional so I've found this site for business cards. They look and feel professional and are a good price too. They come in regular size and mini size, which are about half the width of a regular card. The good thing is that you can use as many images as you like for your cards and also have a logo/contact info printed on the back.
