1. Start with a simple subject. A still life or landscape is a good choice for a beginner.
2. Choose a limited palette of colors. It is easier to mix colors when there are fewer to choose from.
3. Use a small canvas or piece of paper. A larger canvas can be intimidating for a beginner.
4. Use thinned down paint. This will help you to avoid making mistakes and will make your painting process easier.
5. Don't worry about perfection. Just relax and enjoy the process of painting.
