Copyleft hat pattern?

[vampira93.livejournal.com]

Hey everyone. I started a project called Hats for Humans for a school project. Basically I crochet hats and give them to people who need them that I see in my town (Oakland). I am putting together a little zine to hand out to my classmates and others that will show them what the project is, and how they can do it themselves.

Do any of you have (or know where I can find) a hat pattern (hopefully one knit, and one crochet) that I won't get sued for putting in my zine? I don't want to just "borrow" one off the web.

Thanks!
