If you draw on a T shirt?

I just bought an expensive shirt and I want to write some words on it. I want it to be temporary and I know there are special markers for T shirts but there were none at the store i was going to. So I went to all the other stores and they didn't have them either. My friend said I could use crayola washable markers but I don't know if the marker comes out. Like I said, it's kind of expensive. So i was wondering if you know any markers that come out all the way or if you know if the crayola washable markers come out of t shirts. By the way it is 66 % cotton and 34 % polyester. *BEST ANSWER GETS 10 POINTS*
