ooh! i've been wanting to do t-shirt stenciling for weeks. i've got tons of great ideas... its so rad! you can just use fabric spray paint which works very well, buuut you have to be careful. if you get it too close, it will run, and if you get it too far away, it will go outside the stencil and get all over. your best bet when using spray paint is simply to put something down around the stencil. anway, yeah.
