While wracking my brain for creative business card ideas that didn't go too over the top, I thought about using my personal "ear" logo in a way that evoked my interest in 3D visuals (and also presented itself as an obvious ear to viewers of the business card). I eventually decided to go with a simple pop up design that could be easily folded; however, I currently have to cut out every single card (despite my extensive X-ACTO knife cutting experience in college, I am absolutely terrible at cutting thick paper, sadly). Got a recommendation for a die cut printer? I'm all ears (pun intended). Regardless, this has been a fun experience, and playing with little projects such as business cards always makes for a good design exercise. Just wondering how viable it will be to hand this baby out all over the place...maybe I'll get a normal version professionally printed, too.
Speaking of your typical business card, gotprint.com has some great paper weight options at really reasonable prices. I recently ordered some samples (thanks to designer Roberto Blake's recommendation), and was really impressed with the print quality. Definitely going with them for typical printouts.
