Water colors are exhilarating and could be exasperating. This one was done at 7:00 in the morning.  The drawing was made the  day before, because I knew I would have only an hour of the light I wanted.  Capture all your colors in the first hour and gear the colors applied later to them.  This way you can still finish a picture as the weather changes.  Always use a #300 paper unless you like going through the hassle of taping down wet paper with a water glue tape.  I can wet down #300 paper and hold it in place with closes pins without it buckling.
