One in my series of country clothesline watercolors. I used my favorite blue, Schmincke Paynes Grey Bluish, for the sky and the sheets...very diluted of course. For trees and branches, I usually start off with a greyish-brown sepia wash. When that is dry, I put a burnt sienna wash. Then I follow with a dark burnt umber shadow pattern. Sometimes I will drop a green into the trunk, for variety.
