Thanks for the comments. I do enjoy the time spent out there.
Yes, that is pieces of cattle panels. I used to have a small plant shelter constructed of cattle panels. When I moved into the GH, I tore it apart and have used the pieces for all kinds of things like trellises. I've also used them for planting grids and raised them over planted beds to discourage cats until the beds fill in. Cattle panels ~ 1002 uses!
I apologize for not thinking about this when you mentioned needing some place to hang baskets. If you try something like this, I found angling the bottom out will hold them a little more securely.
Seeing as necessity is the mother of invention, I'll be curious to see what you design. Good luck with the little whine...
Perhaps you can see the cattle panel better in this photo
