Hello RPF, for my next project I will be taking a break from the halo universe and making legit Ghostbusters costumes for my twin 6 year old boys. I started the proton packs this morning, scratch building from Styrofoam, craft foam, and random objects. I need to source out the patches and name tags if anyone can suggest a good source. I'm having trouble finding khaki colored jumpsuits for kids, but I might just go with OD Green as I've found a pretty good looking one. Anyway, here is what I have so far. The basic housing of the proton pack cyclotrons.
