Greetings! So for a year I've attempted to do a ROTJ/SE Boba Fett build. At First, I made the first batch of armor out of 10mm EVA foam. I did not like it at all. It was too small and thick. I did a second attempt at the EVA foam armor, this time I made it bigger and I was still unhappy with the results. I then used a ABS like plastic for the armor and this time it was pretty descent. Although, I wore this armor for a inspire Boba 1313-like suit ( My first cosplay suit.) I had a BIG issue with the armor plates. They didn't stay at the proper position it heat formed them in, they would over time expand back to its original state and would get flat. Recently, I had got back to attempt again on my Boba Fett build. I thought about using sintra because I've been doing my research and I hear a lot of positive feed back on different sites. Most folks say that sintra is really good especially with Mando armor. Although, I cant seem to find it anywhere in my local shops. So, my question for you guys is: What material should I use and How thick should the material be for the armor.
