Van Gogh, the famous Impressionist painter, always sketched on his canvas before he started painting. You don't have to learn to draw in order to paint, but if you want to be like Van Gogh, you'll want to learn to draw as well as paint. There are drawing lesson apps like How to Draw - Easy Lessons that give you step by step instructions on how to create drawings on various categories including flowers, animals, and cartoons. Drawing apps give you the advantage to study from start to finish the process, so you can learn the practical skills of drawing. Moreover, apps for sketching for beginners like Artflow give you a lot of brushes and tools to learn to draw without spending money on purchasing the tools yourself. 

In fact, the same way apps can help you learn to draw, they can also help you learn how to paint on canvas. One of the best ways to learn to paint is to use acrylic paint. Acrylic painting on canvas dries quickly and works well when combining primary colors to make secondary colors. This allows you to be more creative with your paintings by creating new colors without having to purchase the spectrum of colors. You can use paint apps like Acrylic Painting which features lessons on how to paint with acrylic. This is perfect for beginners as it gives you private painting lessons and allows you to go at your own speed. 

In comparison, learning to paint watercolor is also good for beginners as it is easy to clean up. It is a different style of painting compared to acrylic, but if you like the look of watercolor, you can look for free online painting courses that teach you the basics of watercolor. Painting tutorials online make it very easy to stop and go back to different sections so you can make sure you grasp each technique. Similarly, you can use apps like watercolors painting to learn painting step by step and enjoy your new hobby on your own time.
