A few months ago I was at a presentation by a marketing consultant. At the end he asked for everyone's business card for a little experiment (what a great way to collect cards, I thought - duly noted). He then asked a volunteer to close their eyes and take the cards one at a time, and give feedback on what the feel of the card said about the owner.
Well, there were all sorts. Flimsy, cheap, worn out, lightweight - and I won't say what she said about the cards! Of course, there were some she liked. Glossy finishes equated to 'polished', thick stock was associated with reliability and professionalism, and so on.
