Structural Weaves- Decor Ideas?

I have taken about 6 basket weaving classes and am looking to go rogue! I am planning a large holiday party and want to spend my summer and autumn nights creating fun and whimsical decorations. I was specifically looking for some standing trees. I have seen 2-dimensional trees in various forms with a simple willow frame, but I'm looking for something a bit more conical and upright. I don't mind ribbing, though not my fave, and I probably won't be able to find any willow (which seems popular), so I am looking to use some round reed- probably #2 and #8. Also, exploring the use of seagrass or rattan?... Anyone wanna help a girl out with some ideas?
