Fold this charming 3D paper cruise ship with a smokestack, pennant flag, and lifebuoy!
Take a square sheet of white paper and fold diagonally across both axes to find the center.
Fold the top point down past the center line to begin shaping the ship's bridge structure.
Bring the outer corners inward, crisping the folds to create the upright smokestack and hull.
Fold the bottom edge up sharply to create a flat, stable keel so the ship stands upright on desks.
Sketch dual rows of round portholes, a deep-blue deck stripe, and a classic lifebuoy ring.
Top off the mast with a red origami flag and set sail! Perfect for cards, gifts, or water play.
