Here are the colors I used for this project (you can use any color that you prefer)
Deep Midnight Blue
DecoArt Extreme Sheen 24K Gold
To start the project, I taped off the roof lines and painted them all Lamp Black. Once dry, tape off the house line and paint one house Deep Midnight Blue, the one with the star Calico Red, the house with the flag Light Buttermilk, and the tall skinny house with Khaki Tan. Paint the star 24K Gold. Paint the flag Light Buttermilk, then paint the upper left corner with Deep Midnight Blue, and stripes with Calico Red.
When everything is dry, stencil stars on the Deep Midnight Blue House, U on the Calico Red house, S on the Light Buttermilk House, and an A on the Khaki Tan house.
Finish with your favorite varnish.
For a final touch, I had some red, white, and blue ribbon in my stash at home and used a hot glue gun to glue it in place across the roof and house lines.
If you want more detail, you can shade and highlight your houses, but I was going for a simple primitive look. You could even sand the edges for a more worn or rustic look.
