A paper dummy is a simple folded model of a publication. It does not need finished artwork to be useful. Blank sheets with rough labels can help you think about sequence, page turns and the overall scope of a small project.
Begin with the smallest version that can communicate your idea. Place short notes where the opening, main sections and closing pages might sit. Turn through the model as a reader would, rather than considering every page as an independent composition.
Look for moments that feel abrupt or repetitive. Move a section, reduce an opening or leave a quieter spread between two dense passages. These changes are easier to discuss when everyone can handle the same modest physical model.
Keep the dummy after the digital layout develops. It records the early structure and provides a useful comparison when the project becomes more detailed. The model is a working question about the publication, not a promise that every page must remain fixed.
