Ok, so here is a little creative idea that you can consider for your next businesscard design.
Here is my simple idea. In the photo you can see an example. When creating a business card design, a lot of times it is useful to incorporate some unique design elements on one or both sides of the card. This is for the reason to make card more visible and easily recognizable for those who will have them. When I was creating a business card for Pro Auto Body, I put a half of a wheel on a side of a card, so when one has the card in his wallet, it is visible, memorible, and more enjoyable to take out and use.
Some people have a lot of stuff in their wallets, and I found this useful to use this idea that would help the card to stand out and not be just some plain color.
