Stencil help

[slitmythroatred.livejournal.com]

I need some help.
My friend's birthday is coming up but we aren't going to see eachother over our spring break. And her birthdy is over spring break. The last time I'll see her is Tuesday. So I have to get her present done by then or a little before then. I want to make her a shirt. We both love The Brendan Leonard show and in an episode (the camp jinx episode,incase there are some brendan leonard fans in this community) Brendan goes "I'm a lemur" and does this little hand motion. We both think it's hilarious and everytime theres a akward silence we do that. So I'm going to make her a shirt with a lemur on it and next to it right "I'm a lemur" Only problem is...
I don't know how to make stencils. I just need a stencil for a picture of a lemur because I think I can manage to make one for the words. So how would I go about making a stencil. Any help is appreciated.
