i saw a method of making armor using a thrash can method *don't laugh* and i can't heat it .
Trash can armor will never be laughed at; the method is genius, especially for those with a low budget, be it due to no job, or tuition for your kids.
As for heating it, I use a hair dryer set on high. Blow the plastic for a good few minutes, until it gets almost too hot to touch, all the while bending it in the shape you want. After a few minutes, dunk the piece in cold water (while still bending it in the form you want).
Some pieces of armor are too large for a pot or pan; personally, I used the cold water faucet in the bathtub. The plastic should hold its shape just fine.
