Use a sheet of paper (8.5 x 11 in or A4 works)
Fold the paper in half lengthwise, then unfold
Fold the top corners inward so their edges meet at the center crease
Fold the paper in half along the center crease
Fold down the top point slightly to form the nose
Fold the wings down so the top edges align with the bottom edge
Crease the wing folds firmly
Fold up the trailing edge of each wing slightly to add lift
Optional: Make small adjustments to the wing tips (up or down) for stability
Optional: Add a small crease near the nose for a sharper point
Test the plane and adjust wing angle until it flies straight
