How to Make a Ninja Mask?
You can quickly morph a black t-shirt into a ninja mask! Take the shirt and turn it inside out. Then, put the shirt over your head and pull it halfway over your face. Take the sleeves and tie them together behind your head. Roll the top of the shirt in towards your head and tuck it in. Do the same with the lower part until you can get it over your nose. Add some black pants and a long-sleeved black shirt and you’re a stealth ninja!
