Comment on Making of, Amidala Headpiece by Riluna

I have been looking allover for a proper Amidala head-pice, not the thin plastic one, and this is by far the best. I'd love if you could make a simple how to or something to get me started so I can make my own. If you don't mind.

What sort of materials did you use? Specially to make it in to the proper form, like in the top pic on the right?

Hugely impressed with this, if mine will look half as good as this I'll be thrilled.
