Today I stumbled across this blog with a great tutorial for creating a stylish straw hat for your dolls and figures.
How to make a doll's straw hat
Depending on how you embellish the hat, you can create some very different looks!
UPDATE April 2013: Apparently the blog with this hat tutorial has gone offline. There's another doll's straw hat tutorial at A Doll Dresser. (scroll down her page a little to find tutorial).
