Re: I can't figure this out...
Have you kept a copy of the coloured drawing on paper so you still know where the different colours are meant to be? Yes, you do lose the drawing on the block but the next parts of the cutting are drawn on again.
I have one drawing coloured in so I know what the finished image will be and one drawing, lines only, on tracing paper which I use to transfer the next lines for the next cutting for each colour change.
