Curious about this one. Back in uni, unless I was doing something with stock images, everything I did I drew out myself. I'm not too good in Illustrator, that's still a bit of an ongoing learning curve, but I generally used that to come up with something myself. A friend of mine - who is now working in the industry - often used royalty free stock vectors/templates/resources etc. save him drawing out something himself. Do any of you guys do that?
