  Pencil in the horizon line, which is the line where the grass and the sky meet. Make the horizon line straight or mountainous.
  
  
• 2). Squeeze a small amount of ultramarine blue paint onto the paint palette. Squeeze a larger amount of white onto the palette.
  
  
• 3). Mix a small amount of ultramarine with white, using the palette knife, until you have a very light (almost white) blue color.

  In nature, the sky is lighter at the horizon.GAR??A EM PLENO V?"O image by P??MELA TORRES from Fotolia.com
  
  Use a medium-sized flat brush to paint along and slightly above the horizon line. Skies are lighter in color closer to the horizon line.
  
  
• 5). Mix more ultramarine paint in with the light blue until it is one or two shades darker than the previous blue. Paint above the lighter blue with the darker blue, blending the colors together where they meet.
  
  
• 6). Repeat Step 5 for each "layer" of sky. The sky will be a medium shade of blue at the very top of the painting. Make sure each layer is well blended into one another for the smoothest appearance.

  Clouds can be puffy or wispy.leaden clouds. grey clouds and blue sky image by Aleksandr Ugorenkov from Fotolia.com
  
  Dip the ends of a fan brush into the white paint, and lightly dab against chosen areas of the sky to represent clouds. Make the clouds puffy or wispy. Let the clouds blend with the blue of the sky for the most natural appearance. Let the sky dry.
  
  

Green Grass

• 1). Squeeze a large amount of veridian and a small amount of light cadmium yellow onto the paint palette. Mix the yellow with the veridian until you have a deep yellow-green color.
  
  
• 2). Paint the entire grass area with the yellow-green shade, using short, upward strokes with the hog-bristle brush. This is the underpainting.
  
  
• 3). Mix a small amount of white with the yellow-green until it is one or two shades lighter.
  
  
• 4). Paint individual grass blades scattered throughout the underpainting, using short, upward strokes with a thin, round brush. Mix more yellow with the lighter shade of green, and create more individual blades in the same manner. Scattering random individual blades combined with the bristle brush strokes of the underpainting creates the illusion of grass.
