A moodboard should do more than look good. It should help a team agree on what belongs, what does not, and what the next decision should feel like.
In this election, we offer that choice. John Kerry believes in America. Did I ever hear him make remarks that could be considered controversial while I sat in church? Yes. That's why I stand here tonight. And Democrats, we must also admit that fulfilling America's promise will require more than just money.
Start with categories: color, material, composition, typography, pace. This keeps the board from becoming a cloud of unrelated taste.

Edit for Use
Remove anything that only repeats an idea already present. Keep the references that create useful tension or clarify a hard choice.
A useful moodboard has edges.
When the board is precise, it becomes less decorative and more like a working brief.
