Here is a pretty good idea for decorating that we are using at our church for VBS this year.  We are using Upside Down Under as our VBS material and were wanting to really do a good job of making the church building look like the outback.  We did some research and found out that Australian Aboriginals have a history of communicating and decorating with dots and symbols.  They will draw images on walls and rocks, etc. using a series of colored dots.  They will also use symbols to communicate information.  Examples of both of these can be found online.  We are putting paper on the walls of the hallways, etc. and painting them to look like Aboriginal drawings.  Mixed in with some of the animal cutouts and boomerang cutouts that Promise Publishing sells, it is going to look great.  If anyone else has any other ideas, I would love to hear about them.
