Here are some of the business cards I have designed.
Some are single-sided.
Some have text or images on both sides.
It’s up to you, whichever is best for you.
Some people say we don’t need business cards anymore. But we seem to be reluctant to let them go. They are easy to give to others, you can write on them (if there is any room left!) and sometimes they are just nice to look at. And touch. And they are a way of making sure you are consistent with your branding and helping people to remember you.
