Senario: You’re designing some type of user interface. Clients never know what they want (even when they think they do) so it’s usually a good idea to come prepared with a basic design to go off. You quickly whip together something in photoshop and think you’re good to go. This is how the conversation goes: Me: I threw together this mockup of a potential design. It’s very rough so just look at the basic layout and ignore details.
