mass effect 2 n7 build....please help

hi, i finally found some templates for making the mass effect 2 armor. i've never done this before and my little nephew seen a picture of this and asked me to make it for him.
so i'm gonna build it. every link on everything i find is completely dead.

where do i start at now that i have the templates. this is for a ten year old and i'm still trying to search how to make it the size to fit him....
i would really appreciate any help from anyone. i'm sure i'll mess up on pieces, but it is only just foam and it's for a ten year old boy that really just wants to wear a cool costume and run around in with his new nerf rival gun i got him for christmas......it's the automatic one that holds a 100 bullets....

thanks again

Hi Jasel,

You can modify the armor pieces in pepakura designer (free software) by clicking 2d menu and then change scale in submenu.
Just in case you lose your files:
