wow. i have this really awesome idea. to make stencils to spray paint images onto my old jeans/shirts/anything.

has anyone done anything like that? im thinking razor blade the picture out of oak tag, but i dunno what kind of paint to use. regular hardwear store spray paint? do they make fabric paint in spray form?

thanks for any imput.
