Business cards are the best first impression of any business! The style and design tells current and future customers, how professional the business is before they even starting dealing with that business.
A professionally done and eye-catching business card can draw in a pretty good crowd.
That's the approach I take when designing a business card. I always strive to design a look that jumps out at you and makes the recipient look twice or at least longer than usual.
The design has to be bold and inviting, but still solid enough to not over-shadow the information for the business.
