Ok, so my first go at this wax resist technique didn't quite turned out as expected, so on to trial no2.
This time I really put a thick layer of crayon on my blank page, it was easier to remove the paint as with the previous prints but still not exactly what I had imagined (I also find the colors rather dull)
I also tried something different, I made a print on which I rubbed with a candle. Removing the paint was easier but it was harder to find the spots where I had rubbed. I also should have chosen more contrasting colors. I do like the feel of the spots where the wax was rubbed.
When I pulled the ghost print there was also a transfer of some of the crayons of a previous print
