This was an interesting project, one that combined a number of different elements.
The base was the first piece, which you can see in this facebook live video:
The flags were created by taking sticky printer labels and wrapping them around the poles. This made them very flexible but sturdy, since there were now 2 layers of that printer paper, stuck together!
These views show a little more of the waterfall base, made of bark and branch.
As far as the color scheme goes, it was pretty traditional Green Knight fare, but with a twist of the fluorescent green sword.
