I think it encourages me to do abstract art on paper and could be a great way to work a piece quickly before breakfast a la Pollen.
Below are some trial areas using water soluble crayons and wax.
Other images are of pieces that used soluble graphite, crayons, wax and aquarelle pencils. Not sure I like the pale effects and the way some of crayons are softer than others, but I guess you would get used to them if used frequently.
Interesting though, especially when texture is added using wax crayons of various colours.
I also like the way it is possible to pull the colours into each other or scratch away parts using pencil crayons, aquarelle or simply water.
Like others who speak online, I didn't like Copic markers on this surface.The surface needs a fixative to make it stable.
