Nobody's going to deny that a good story needs well-fleshed-out characters. This Inspiration for Writers site features an extensive character trait chart. While I think that it can be useful and probably even a good warming-up exercise, I'm curious to know if many of you out there have used these for writing, and if it has helped you to go so far as to detail your character's eye color, brand of car, and smell. And, after you've taken the time to detail that, do you feel obligated to mention that Blued-Eyed Mary drives a Kia and smells like vanilla?
