I'm very impressed, you got a really good bend in it. How many times did you need to reheat the sintra? Great job!
I had to reheat it a million times it felt. I set the whole thing on top of my kerosene heater cage till the whole thing was pretty much a wet noodle, then I'd throw it on my back and start shaping it out. Pretty hard to do by yourself

It was a lot of trial and error. I'd get part of it shaped on the back, but bad on the shoulders. Then I'd heat it back up and get the shoulders good, but the back would turn a little off. Honestly the shoulders seemed the hardest, to get it to hug your shoulders and back at the same time without parts not sitting snug to your body and looking ackward. Starting my painting last night, but ran out of US med green
