Lesson

Test before anyone else sees it. Make a test sheet, one artboard with the mark at every size the brief named, from the smallest use to the largest, plus the hardest material. The Branding course sets the rules that come out of this, such as clear space and minimum sizes. This lesson is the testing itself, and the decisions it forces.
