Three tips for painting with watercolors

1. Watercolors are very difficult to correct. Start painting from the lightest to the darkest tone.
2. Use a paper with a lot of cotton to better support the load of water, heavyweight fabriano is a very good choice.
3. Before jumping to paint something concrete I recommend that you experiment with different watercolor techniques on a piece of paper: use a lot of water, use little water. Paint wet over another color, do the same when the first color is dry. Try everything you can think of or see in tutorials so that you become familiar with the technique and can work with more control over the medium.

Bonus: complement the watercolor with colored pencils to add texture to the painting.
