you'll need:
markers, alcohol, cotton, glass and paper.

how to:
draw with the marker on a glass (can be your window if you have nothing else. and the marker must be water based). place the piece of paper on top of the drawing. gently rub the cotton with alcohol on the paper. the image will transfer from the glass to the paper.

try this:
put a photo or a drawing under the glass and draw over it, but draw it in a different way than the original.
transfer more than one time on the same piece of paper.
use more than one color when drawing and then transfer.

it's a lot easier when you don't need to hold the camera wile doing it.
