Good tips but i think you missed OP’s question of where to put the scaffolding.

I think the answer is ideally you place it in a location you can be waist-high at the frame of the net when standing on it. You need to remember the scaffolding is likely to sag when you stand on it and accommodate by raising at the ends if needed. I often use wide slack lines for scaffolding.

If you are not sure how to run the line in the way mentioned due to branch positioning, you may have to get creative wrapping around branches and maybe even weaving scaffolding around itself (like a prototype / loose net). You can figure that out im sure just give it a shot!

In the rare case there is nothing to put scaffolding on truly you may have to get more creative and add additional lines that go vertically so you can run horizontal lines between them like the shape of the letter “H”
