To make a ninja costume, make a set of ninja stars, secure a T-shirt as a mask over your face and head, and put on black clothes. Finish the costume with a red sash with the stars tucked in and a costume ninja sword.
- Make ninja stars
Make a template for ninja stars, and transfer it to a piece of cardboard. Cut out the stars, and wrap silver duct tape around them. Repeat this procedure for as many stars as you desire.
- Pull the T-shirt on for the mask
Pull a black T-shirt with a tight collar over your head. Stop when the collar is resting against the bridge of your nose.
- Pull the back up over your head
Flip up the back of the T-shirt. Pull it over the top of your head until it covers the top of your forehead. It should stop just above the eyebrows.
- Secure the back of your mask
Take hold of the sleeves and the loose ends of the shirt. Wrap the fabric around your neck
- Put on black clothes
Pull a black turtleneck over your head, and finish putting it on. Make sure the ninja mask is tucked into the collar of the turtleneck. Pull on a pair of light-weight black sweatpants. Put on a pair of black boots.
- Complete the costume
Secure a red length of fabric around your waist as a sash. Tuck the ninja stars into the sash. Strap a ninja sword to your back.
