My business cards are pretty basic, just a small image on the right side and my contact information, such as email and tumblr!
And it's blank on the back, because you never know if and when you need to write something down!
I'll second Moo.com. it's just a fantastic website, the quality is really top notch! I've had multiple cards with my phone and there isn't any scratch on it YET. AFTER 2 YEARS.
Now THAT is something <3
(also I'm on a borrowed computer so I can't show any pics unfortunately, I'll maybe edit that in later on sunday, we'll see!)
Edit: @shazzbaa omg, I LOVE your business card! It's both humorous AND informative! <3 (I may or may not feel a little bit inspired by you the next time I print a new set ;D)
Edit 2: Found a terrible picture, but I guess you get the idea of it! (back is blank!)
