Turn a familiar paper plane into a small perspective exercise. Separate the two wings and central fold with a single light shadow.
Place the nose and the two rear wing corners. Connect them lightly to establish the overall triangular silhouette.
Draw the central ridge from the nose toward the rear. Connect each wing edge to it so the paper planes stay readable.
Use a light even pencil tone on the underside. Keep the top wings pale and strengthen only the edges that overlap.
A small thing to tryCheck the corners before darkening any line. Small changes to a corner can clarify the whole folded structure.
