This idea is one I typically use with clients who approach me for creative design work. For logos and the like, I ask them to show me images, designs and color pallets which speak to them strongly. For web design, I ask them to provide me links to sites they use and enjoy, both in design and functionality. This level of feedback provides me with a window into the client and makes me better able to nail their design on the first try, therefore saving them money and me time exploring ideas and paths they’ll likely reject later on. When you charge by the hour for your work, it’s always good to let the clients know you’re working to their best interests, rather than trying to pad or extend the billable time spent on their project. It’s worked well for me for decades now, and I intend to continue working in this manner for my clientele!
