Birch Tree Demo - Page 4

Repeat Step #8, remembering to vary the width of your strokes (use cut up credit cards) and to leave some areas as originally painted. Refer to the photo of the finished painting. Where there are light/white areas, the paint has been scraped out by using the credit card technique.

Then, while the paint is still wet, flood in some darker and more intense colour (richer paint mixture - less water) to show the birch blisters.

Pick a wet edge and deposit some pigment on the dry side of the edge. If you are touching both wet and dry areas simultaneously, you will get a hard edge on the outside of the tree and rich colour will bleed into your wet area giving a soft edge. An interesting combination.
