I want to make hats

I really, really want to make little 1940s hats - any suggestions for instructions patterns etc. are very welcome.
Not tha I can make hats right now, I have to finish the last part of my master's test by making a tunic, a surcoat and a new coif for Rickard. In like two weeks. Unfortunately I don't have any wool that I want to use at home.

Improvements

1. I can buy thin wool from herzeloyde for Rickard's tunic.
2. I just made a new, fitting pattern for a coif for Rickard. Unlike the old one it doesn't depend on pleating at the neck to make it work.
