Just a thought. I looked at a lot of pictures online. There were a lot of pictures of supports that lean into each other at the top.
I drew this right before I saw Saltmarsh's post. It would be using 8' landscape poles and a 2x6 at the top, and then horizontal 2x6es across the top to tie it all together.
Like I wrote, it's just a thought. So what do you think?
