About your backdrops. I haven't done scene work but I have done murals
outside, etc. I use acrylic paints. They are durable and have great colors.
What I usually do is to create an outline in a light color. Have a complete
drawing in color at the site and have the kids follow along with the
example. Give out certain colors to certain kids and have them paint only
those areas. And hop around a bit so that the wet paint is not something
that will get stepped into.
