Sketch in details very loosely. Important not to have

hard pencil lines which cannot be erased after paint

has been applied. You could use a light orange water

soluble crayon.

Wet paper with clean water and drop in lemon yellow

and a bright red. I experimented with permenant

orange. Remove the white area at the bottom with a

tissue. Dry

Turn board around and wash with clean water. Lay

down a wash of cobalt blue. Try not to allow the blue

to run into the yellow (we don't want a green).

Drop in mixtures of red and blue for the bottom of

the clouds then soften the edges with a clean brush

which is just damp not load with water.

Add the foreground with very dark areas of paynes

grey + lemon yellow. You can paint in the road and

houses if you wish

 Darken foreground and put in telegraph wires

with a rigger
