Gelli printing with wax crayon resist

After seeing the tutorial over on the gelli arts website I had to test this wax crayon resist technique.
But as you can see it didn't turn out as planned.

I don't seem to be able to peel of the paint afterwards, maybe I need to build up the wax crayons much more??
However I like these prints, they have something abstract about them.
I'm going to use them to make a gardenbook for my son's progress at a vegetable garden, more to come later.
