I have the small gocco, and I was told at the art store that if I buy the mesh-on-a-roll and a large frame, I can make larger screens than with the pre-stretched mesh, by moving the image around and doing multiple exposures all over the image.
Has anyone here ever tried it? What were your results? I was thinking that you might get 'lines' where there is overlap between exposures. Did this happen to you?
