I was wondering why in the world i used it, but it was what I had on hand.
This is very creative, and I believe it might be intuitive too, because you sort of do what looks or feels right. I am still using acrylics here and there. It makes me feel better, and makes me feel like I am really painting. I am surprised at the rich colors you can get using this method.
I have a new one sketched off. Plus I have been working on some more 'New Spur' paintings.
