I've done some research into materials that were native. That wasn't as easy as I thought it would be. Initially, I wanted to try to use native materials for the build, but ended up going with strawberry guava bark for some of the build, something close to pili grass for the roof, and modern kapa for the presentation board. The moss rock wall in the background doesn't have concrete holding it together, making it a little more authentic.
Our team meets tomorrow evening to see what the next steps are. The paper will also be a challenge to get going. I know we'll make it!
