After the success of "The Dark Knight," every little villain wanted to be the Joker for Halloween. We admit: The Joker is a pretty cool bad guy, but if you really want to impress your friends with your esoteric Batman knowledge, this year you'll go as Red Hood (aka the Joker before he was turned into the Joker by falling into a vat of chemicals). Now when someone in white face paint and green hair sees you and asks who you are, you can say, "The same thing as you, only cooler."
Place the hockey mask on your face. This will serve as the firm basis for your Red Hood mask. With the hockey mask on, wrap the red spandex around your face to determine the amount of material necessary. Use pins in the back to mark where to sew the material together along the contours of your head.
Outline your eyes on the spandex using the black marker.
Sew the back of the spandex together so that it will fit your head as a mask. When sewing, sew through the head strap for the hockey mask so that the two pieces remain together.
Using your scissors, cut out the eyeholes you marked on the outside of the spandex.
On the inside of the mask, glue the white nylon over the eyeholes so that you will be able to see out of the mask, but anyone looking at you will only see the white eyes of Red Hood.
Make small airholes in either the mouth or nose, depending on your preference.
The mask airholes you make should remain subtle. None are visible on Red Hood's mask, but you want to be able to breathe naturally while wearing it.
To complete the rest of the Red Hood's costume, you can follow one of his portrayals. In his original appearances, Red Hood had a red cape and full suit. In later forms he lost the cape and appeared in jeans and leather jacket.
Have an adult assist with the sewing, and be sure not to cut the eyeholes while you are wearing the mask.
