Dowling Design created these adorable business cards for a Garden Designer. They are shaped like the little makers you stick in your garden and the horizontal lines breaking up the contact information even help give it a similar feel.
I really love seeing fun innovative business cards, but there is a downside to designing them. While they are likely to garner attention when handing them out, the drawbacks are that they are harder to slip into your pocket or business card holder when out and about networking, and they also do not fit into traditional rolodexes [some peoples still use them!], nor do they fit into those business card books.
