Hello MLE,
Was cleaning out my computer and found a link to this classic blog post. It is over two years old now, but still good!
20 Things You Should Never Say to a Graphic Designer – But Probably Do.I have heard every one of them from clients many times, as I am sure most designers have. It doesn't bother me too much however, because I am also guilty of saying many of these things to my poor designers! It is okay. No one is perfect. Not everyone is born as an experienced design producer, and even if you were, the design process cannot be controlled all the time. Many of these common asks are possible - granted the time and budget is available, but often this is not necessary. Creative workarounds and problem solving are usually best.
