I am currently making a Warhammer 40K Space Marine costume. Not sure if it will be done when AR comes, but I'll do my best. I just have a couple of questions:
1.) Is it okay to bring a cardboard chainsword and put a cardboard halo on my backpack prop to AR? I'm worried about the "pointy" stuff on those two, but I just want to make sure if it's okay to bring these before I start making them.
Here are pictures as reference:
Chainsword:

Halo on top of the dude's "backpack" (this is not my costume's final design, but it's similar):

2.) What do you guys usually use for padding inside the armor? I can't find any stores that sell Airtex High Density Foam (just like what the tutorials in Youtube use), but I was thinking of going to http://www.foamshop.com/ to get some foam...
Thanks!
