A friend of mine was going to scrap her large trampoline. I asked for the legs as they make a U shape.
I have used 3 uprights and cut one end of the U shape on each section.
The string goes up to about 5' then is angled at about 45 degrees and goes slightly over the path, to make picking easier and dwarf beans are growing underneath.
By the way, it's not finnished yet ;D
