Select artboards with the review question in mind
A Sketch document can contain many artboards, experiments, and components. Exporting everything may reveal unfinished alternatives or internal notes. Identify the screens or boards that answer the review question, and confirm their order before creating a shareable copy.
Use labels that make the PDF sequence understandable to someone who did not build the design. A named flow is easier to discuss than a collection of pages with ambiguous numbers or repeated device mockups.
