Yes, I think so, Tara. I found the 2nd thing looking for pics of the thing/system I saw at the street market in New Orleans earlier this year. It was that same "opening" but they were pieces that could hook together sideways, diagonally, in a diamond. He was asking more than I thought some shaped pieces of wood should be, but now wish we'd at least taken a pic.
Lynn, I like to hang pots from trees too, either from the limbs or hooks attached to trunks. Ever since I discovered the rolled green plastic-coated wire at the hardware store, (under $3 for 25 ft.) I've done some different things with hanging them, and making some longer arms for some. It would be easy to use it to hang classic-shape clay pots by the rim. One could hang those, or any cache pots with a drain hole and a rim.
Between that and the stuff I've seen because of this discussion, I've got ideas to use other items for hanging pots. Like actual cooking pots with ruined teflon (I love a visual pun and I'm sure DH could finagle some holes in them,) wicker baskets coated well with urethane (though would still probably only last 1 season outside,) cute watering cans, a wire ball stuffed with moss/peat, sit pots in a hanging Easter basket if warm enough where "you" are for pots outside at Easter, a plain piece of wood that looks like a swing with the right-size hole(s) cut to hold a pot, something I make with scraps of wood would look better than these plastic things. Not all of these suit my personal taste, but came to mind, so sharing them.
I've never tried hypertufa but if I did, I'd prob make something that hangs.
Good stuff to think about, work on during the off-season!
