The following watercolors were done from photos on Tom Hoffman's Watercolor Homework blog.
For each of the paintings I started with the sky by wetting the area of the sky with clear water then painting cobalt blue on the wetted page. Then that was left to dry. The bottom half was done one of two ways. For one painting I just applied a wet base color. It was the lightest color I was going to use in that area. The other paintings I actually started the same way I did the sky, with clear water then painting over with my yellows and greens. The key to avoid blooms is to not re-dip into water. Be sure that the brush and pigment is drier than the page you are painting on. Using this technique the water on the paper is the water supply that you use.
