Select the subject for your painting. Set your canvas on an easel and squeeze oil paints onto a palette. Dry the toned canvas at room temperature for 1 to 2 days.
Think about what type of landscape you'd like to paint. Do you want to include the ocean, a mountain, or a field? Decide what season you'd like to paint and consider what type of light your landscape will have. For example, if you're painting an afternoon scene, the light might be casting long shadows. To give you some ideas, you might want to paint a bright spring scene of a mountain with pine trees in the foreground. You could also paint a darker landscape of the ocean at sunset with deep streaks across the sky. If you don't have an easel or you're painting a small canvas, you can prop the canvas against something sturdy or lay it flat on your work surface. Then, get out a paint palette and squeeze a coin-sized amount of each color of oil paint that you want to use. Improvise if you don't have a classic artist's palette. Use a smooth piece of cardboard, a flat glass platter, a thin plank of wood, or a plastic container lid. Set the canvas in a well-ventilated room and leave it to dry completely. This should take 1 to 2 days depending on your climate. Then, you can begin to paint the sky on your canvas. To ventilate the room, run a fan or open a window. Remember to clean your paintbrushes and cover the paint palette tightly to prevent them from drying out.
