Modular Paper Football

Divide white A4 paper into four equal strips.

Fold a strip lengthwise to mark its center. Fold it back and forth into a chain of equal triangles.

Open the strip and cut out a complete triangle. Fold each corner toward the opposite edge midpoint, then fold inward again.

Tuck the exposed parts inside, fold the three corners toward the center and secure with tape. Make twenty white units.

Divide a 10.5 cm black square into six equal rectangles, as shown.

Fold a rectangle in half with its opening down. Fold upward diagonally and fold the excess upper section down.

Fold the excess right part behind, open the top layer and fold the lower section back. Bring the top layer down again.

Fold backward and tuck into the lower opening. Turn over and crease the side sections downward.

Bring the pointed corners together along the creases, then fold toward the marked edge intersection. Repeat on the opposite side.

Add tape to the two side tabs and flatten the front into a pentagon. Make twelve black units.

Attach the taped black tabs beneath white hexagons. Tuck a white corner into the black pocket and glue neighboring white corners underneath each other.

Surround each black pentagon with five white hexagons and continue the pattern around the ball.

Join the remaining edges carefully and let the adhesive set before handling.
