Draw with a brush

You have started your painting and being well into the background and foreground you find that you have lost your drawing, assuming you draw the more difficult subjects onto your canvas before you start. In acrylics you can use soft charcoal to draw in what you have lost, then rub it out with a wet paper towel later. However, I prefer to use a very thin brush and contrasting paint soaked with lots of medium to draw in my subjects. I use the maul stick when drawing with paint. The lines go away when I complete my work because I paint over them.
