The long collagraph plate worked - 6 prints and 6 ghosts. Unfortunately I forgot to photograph any before I put them under weights to dry.
I’ve finished the mock up for the other book I was thinking about, also using collagraphs. It’s at the scrap paper and scribbles stage, so not very pretty.
But I did cut and assemble the coloured ‘Twelve dancing princesses’ risograph prints. The offset colour looks almost deliberate when you see them all standing together.
