So, this is an armor piece I'll be wearing to San Japan as well as Dragon*Con.
I'm going as my own version of the Demoman class from Team Fortress 2! As you can see from the orange details, I'll be going as RED Team
Yes, I didn't add his pouches because:
1 : I didn't want them to get in the way
2 : I'm tight on my money
3 : I'm going as a female version of Demoman. Creative Licence?
Anywho, I used the following materials, and it took about, cumulatively, 20 Hours to make everything (From armor, to grenades):
-EVA Foam (Grey Puzzle Piece Mats)
-EVA Craft Foam (Grey)
-2" Black Elastic
-2" PVC and PVC Caps
-2" Black Straps
-Orange Spray Paint
-Spray on Polyurethane
As for how I made these things, I used several tutorials online. Google "EVA Foam Armor"
