Ever wondered what to do with those dollops of excess acrylic paint? Well, I figured it out. When concentrated they are great for impasto work like this. Just paint over the page then scrape off whatever design you think of. If there isn't that much, you can mix it with water and make an excellent wash. And there are a few variations between the two that allow the use of different colours, textures and even brush strokes. I guess I will never have any wasted paint again.
