These are some set design photos from a school play for "Annie" we did a few years ago. My Set Design Club painted the backdrops and made some of the props. At this school, we had two sets of backdrops. They were essentially two huge 1/4" boards hinged together and placed on large caster wheels. They were definitely not the most stable of backdrops I have worked with!
Very top-heavy and tippy....
We painted the board with house paint. Once dry, we stapled large pieces of burgandy fabric to the top. These could be flipped over the boards to hide the painted scene when not in use.
Below, you can see students tracing the initial drawing onto the backdrop. We use the trusty old opaque projector to project the drawing. A digital projector will also work.
Once the drawing is complete, students start the painting process.
We use cheap-o house paint- it's messy. Very messy. No matter how many drop cloths or newspapers you put down, paint drips seem to get everywhere!
Below is supposed to be a 1930's skyline of New York City.
Here's a scene from inside Daddy Warbuck's mansion.
And here's some scenes from the play itself.
