Our current business cards are designed around the idea of flexibility, on the back it has a series of statements that cover most situations, when I give out my business card, I simply cross out the ones that aren't relevant. Another aspect of my design thinking is "Double Use" the idea is that everything has to have another, secondary purpose. In this case, the business card is also a ruler, something I'm often missing. The idea of Double Use comes from working with limited budgets - I work for a number of cultural institutions whose funding is limited and therefore need to get the most of what they have, I also come from a humble background so designing within a limited budget comes naturally to me. My other stationary isn't printed but is just standard white paper and envelopes that I then stamp, I have gotten an ever growing collection of stamps produced so that I have flexibility in how I make my stationary look.
