Ok. so I'm working on the backplate and collar piece and its a pain in the *****. I am using sintra pieces i've cut using a template. I can't tell if the template I'm using is shaped wrong or if its slightly, disproportionately large. when i mold one section, another goes out of alignment. ie: if i fix one shoulder, the other goes askew. my back is V-shaped the armor is box-shaped.
The rest of you who've made your own sintra back plates, can you tell me roughly step-by-step how you measured, cut, and molded it to a fit?
All info appriciated as always.
