This isn't a real answer but... http://theoatmeal.com/comics/design_hell http://theoatmeal.com/comics/design_hell In seriousness, just be aware that sometimes the changes you ask for can seem incredibly simple but have major ramifications for the overall design. Also, treat your designer like he knows what he/she is doing. I don't think there is a designer out there that doesn't want input but to some degree you have to trust their vision even if it doesn't quite mesh up with yours. I also had a client that spent a month tweaking and tweaking (make the logo bigger, move it over about an inch, add this below the logo, etc.) and then was surprised when their website wasn't available on time. That can be frustrating even if you're getting paid hourly.
