The design process can go on forever. So when it comes to working with a designer, after you’ve gone out of your way to hire one, as a client, here’s a bit of advice for you. Designers work with you to realize your vision and execute it visually in the best way possible. If it comes down to the end and you, the client, just can’t make the final decision, then simply defer to the designer. The one with the expertise whom you’ve hired. Do that and things will get done. If you cannot do that, then you need to rethink why you hired a designer in the first place.
And then defer to the designer.
Seriously. That’s the only the design process will end well. Otherwise, the final product will be a cobbled together pile of mush uninspiring to all people who come into contact with said mush.
