Use origami, the Japanese art of paper folding, to make a paper helmet in the style of the famous helmets worn by the samurai, called kabutos. These helmets are considered the central focus a warrior's entire armour. This helmet was even the inspiration for Darth Vader's helmet in Star Wars, according to the Star Wars website. You can use traditional origami paper to make a miniature helmet or larger paper to make a helmet that you can wear around the house.
Pull the top right corner down to the bottom left corner. Make a diagonal crease that goes through the middle of the square. You now have a triangle.
Turn your triangle so that the crease lies in front of you horizontally. Fold the right corner up to the top point of the triangle. Crease firmly into place. Repeat with the left side. You now have a small square turned up to look like a diamond. The two corners that you just folded upward make two flaps.
Fold the top point of the right flap in half downward. Repeat with the left flap. Take the flap that you just made on the right side and fold the bottom point a half inch out to the right. The result is a small obtuse triangle. Repeat with the flap on the left and create another obtuse triangle.
Take the top flap and fold it a half inch from the bottom. It now conceals a large part of the bottom portion of the piece. You still have a final top flap remaining along the top section of the piece.
Fold the crease the runs horizontally through the middle of the piece 1/4 inch downward. This is going to be the brim of the helmet.
Pull the final top flap down to the bottom point of the piece. Make a strong crease. Unfold the flap. Slide the flap into the interior of the helmet, tucking it in there so it's hidden completely.
Fold the right corner of the helmet upward 1/4 inch. Repeat with the left corner. This will help open up your helmet and give it stability.
