But I couldn't have written it any better than Seth Godin did in his latest post, How to live happily with a great designer.
The gist? Trust your designer. I have been preaching this lately because I have seen less and less trust and more and more micro-managing.
My favorite is no. 8:

This is a must read IMO. Please pass it on to every editor, marketing director and author you know.
