I thought paper stock weight was just a number until my business cards felt like cereal box cardboard
I ordered 500 cards on 16pt stock from a shop in Austin to save $40 and when they showed up they bent like a cheap coaster. A printer there told me 32pt soft touch was the standard for anything you hand to someone, so I paid the extra $60 and the difference was night and day. What weight do you actually run for client cards, or am I the only one who had to learn this the hard way?
