Putting your pigments in the same spots each time speeds
up your process. And putting out all of them when you start ensures that you
develop the painting based on what you see, rather than on what’s at hand. Be
sure to replace a color when you run out, not when you think you’ll next need
it.

2. Value drawing of the scene in question, in your
sketchbook.
If you do this on your canvas and then paint over it, you
won’t have it to refer to when the light changes or you need to restate
your darks. Keeping it in your notebook means it’s always accessible.
3. Crop your drawing, and identify and strengthen big shapes
and movements.
If you start by filling in a little box, you only allow
yourself one way to look at the composition. Instead, draw what interests you
first, and then contemplate how it might best be boxed into a painting.

4. Transfer drawing to canvas with paint as a monochromatic
grisaille.
This allows you to draw with a brush and check your
composition’s values.
5. Underpaint big shapes making sure value, chroma and hue
are correct. Thin with odorless mineral spirits (OMS), turpentine, or whatever
solvent you generally use.
This underlayer should be thin, but not soupy, so it can
accept top layers without making mud. You don’t want added oil or medium in this layer
as it can lead to cracking in the future. How much OMS? That varies by the day,
but just enough that you can drag your brush without scumbling.

6. Second layer: divide big shapes and develop details. A
slightly thicker layer.
This is the body of your painting, without a lot of detail. Use almost no OMS, and no painting medium or linseed oil. It’s still too early for impasto. For some painters, this is combined with the last layer.

7. Third and last layer: use medium and more paint, adding
highlights, detail and impasto.
This is the final layer, the one with painterly
flourishes. Controlled use of medium here results in an even, bright, tough
final surface.
