Believe it or not, the urban backyard in Rear Window has a white picket fence around the Sculptress’ garden.
Here is what a fence looks like after being aged. First layer was white acrylic paint, followed by sponged on light gray. Then a thin wash (black or gray acrylic paints mixed with water). The wash should be very thin, just enough to add some color. Brush it on and then immediately blot it off with a paper towel. Evaluate all the pieces next to each other and make them match.
