Inca, Mayan, and Aztec Decorations?

I have a world history project about the pre-colonial Americas and we have to decorate our cl with things from the Mayan, Aztec, and Inca civilizations. We are already planning on having a table for human sacrifices, and I was wondering what else we could use. I was thinking that we could use those gr hula skirts and d them around the room, but I was wondering what else we could get that is cheap and would look cool.
