Welcome to the FISD, Jonathan! Lots of great info. given so far, and know that we are here to assist you every step of the way so never be shy about asking us anything. I know what you mean about the OCD thing.. believe me. It took me 3 months to build my first set of armor, but as someone very wise reminded me way back when "It's a marathon, not a sprint". Purchasing a set of commissioned armor is fine and dandy for many, but often there are little nuances that need to be fixed/adjusted. We can help, of course.
Building your own takes time and patience, but in the end you will have a custom tailored costume that fits you to a tee. Plus, if there are ever any issues you know how to fix/repair them!
Best of luck on your white armor journey!
