Here is my response to Dorene's question from my online lessons.

What does the term "keep it fresh" mean?
'Keep it Fresh" means put your washes and glazes down directly on the paper. Don't mess with it until it's dry.
In other words, don't do anything to your painting while it is drying.
Although you could apply a little more pigment to the wash or glaze as long as you have more pigment than water in your brush. That takes painting experience.
Hope this answers your question.
