Giving Sintra armor depth.

Hi im new to armor building and im doing a bunch of research before i start working on my first project (WarMachine).

I was wondering what techniques ppl use in order to give certain parts of the armor depth. Do you just layer it? Or do i just need to get really thick sintra? Or do i need some other material to put between the pieces. Pleeease helpp.

That all depends on what your going for. You can do both , you can use thick syntra or you can use thin layers and double them up. Don't forget to use a dremel, it does wonders.
