This is going to be an interesting project. The goal is to have an ecstatically pleasing piece for the front yard that is also functional.
My plan is to have like an outer vase around the tower to hide the white pipe. The media is going to be LECA but the whole structure will need to be weighted down with some heavy pebbles to avoid it from tipping over.
I'll be working on this piece for the next few weekends and I am very excited to see how this goes!
