How to make the Bridge To Terabithia crown?

Have you guys seen the movie Bridge To Terabithia? Well almost at the ending of the movie Jess brought his little sister May Belle to Terabithia and then you’d see Jess putting a crown that’s made out of branches on May Belle’s head.

Here is a picture of the scene with the branch crown: http://tinypic.com/r/hvnry9/4

I was wondering, how can I make a crown like that? We are doing a haute couture for art class & that is something what we need. So if anyone know how to make a crown out of branches like the one in the movie please tell me. Thank you before hand.
