From this I got the idea of using oil pastels in a similar way. I coloured thick areas of oil pastel on one page, then drew on the back of this area to make the impression on the next page. The advantage of this in my mind, is that it is not a mirror image as in the print, but the same way round as you draw-so more of a transfer I suppose. This makes it good for doing writing. I have not tried this technique before and have not seen it, though I am sure it has been done! Tonight I carried on trying it out and then added watercolour. Another thing I liked about these in comparison to the prints, is the water resistance of the pastel as opposed to the solubility of the printing ink. This is sounding more and more like a science experiment!
