Change your brush
Sometimes we all have days when everything we do ends up in the bin.
On days like these you need a change - the easiest way is to use a different brush or other implement (sticks, sprays, toothbrushes, paper, plastic wrap, masking fluid, masking film, knives, watersoluble crayons, oil pastels, pen & ink (lots of ideas). Turn your paper over and tell yourself that it's already ruined and nothing worse can happen. You will be surprised what you will learn.
Here are the figures and the brush I tried painting them with. (a one inch wall painting brush!) Just to see waht the result would be. (there is a painting I don't like on the back!)
