Please do! I'm writing down notes right now.
First you need Cyanocrylate to add the threads on the costume
You will need vallejo paint or similar
Gauze for the costume
And the magic, WIPING CLOTH!!!
The body will be the joe trooper because i have some of them and its also green.
first drill the head in the nape
Be carefull when you do this
Put it back on the figure
And now you can do the sniper pose
Then take a head from a PTE figure and take out the "bonnet"
Cut the gaize similar to the body and add some elastic like the ones on PTE backpack
The threads are added on the gaize with cyanocrylate but the elastic was added with needle and thread by my girlfriend
Each thread has 2 to 3 centimeters (about one inch)
