This is my tutorial on how to make a Halo 4 Master Chief costume/cosplay. The main building material will be EVA foam and craft foam for details. The EVA foam can be bought almost at all home improvement stores and the like. I will be using 1/4" EVA foam from a foam shop nearby. The craft foam can be found at Michaels, Ben Franklin and other craft stores.
The other materials/tools are
-A carpenters knife
-Hot glue & Glue gun
-Paper, pens, ruler etc.
-Spray paint-Krylon Italian Olive
-Small lights(led's or miniature christmas village spotlights that can be bought at miachels around christmas time.)
Step 1: Guide Pictures/ Objects
Instead of using pepakura, I made all the parts from scratch as I found out that pepakura is insanely complicated. Though pepakura can be useful for guide pictures/models. After my computer crashed on me, I went to use a master chief action figure that worked pretty well.
Step 2: Making the Cardboard Frames/ Templates
For the Chest/ Torso I made a cardboard model of the piece first to make sure that it fit ( since I don't have unlimited EVA foam) then traced out the pieces onto the foam and assembled. With the helmet I made a base piece out of cardboard that just added durability/ stability then added craft foam and EVA foam to complete. For the cardboard frame, I made small(ish) boxes to hold the lights in the helmet.
Step 3: Making the Rest of the Armor
For the rest of the armor, I made the base piece(s) out of EVA foam and the details out of craft foam. As an example, the thighs were one piece of EVA foam just wrapped in a circle.
