Alcohol Ink on Yupo 
When I put the yellow ink down on top of a glaze of blue, the lines were as fine as pencil lead. But as it dried, the yellow pushed away the blue, mingled with some of it and made the image you see here. 

One more image remains in my bag of tricks. Oh, I painted a LOT more than these, but I will save them to post when I have a large project on my easel.
