Thanks Birdie and Cheng!
@Cheng: I was originally looking for a hair bun hood, and I found this hat! The problem when you Google Qin warrior, is that you always find the terracotta statues, and nothing more. I can't remember what I eventually typed to find this one.
Then, I searched for a nice dragon that fitted the sides of the hat, and learnt how to project a design upon another!
Tricky. But when I knew how to do it, I was able to make those decorated Hoplite shields!
