Tiny pivots, gathered ribs, brass-like dots, and the point where the fan begins. Keep the writing focused on visible folds, paper texture, arc shape, rib spacing, printed marks, and soft shadow.
Keep it decorative, not instructional.
Porcharo works best when the fan is treated as a still object or surface detail. Write around shape, repetition, shadow, color, and the quiet pause of a half-open form.
Use calm object language.
Good wording: folded paper, fan ribs, scalloped edge, warm surface, hinge point, printed panel, arc shadow. Avoid how to make, how to use, cultural explanation, festival coverage, product review, or buying advice.
