Hi Leslie, We used cement rebar, or at least I think that is what it is called. We got it at Home Depot, and it wasn't very expensive at all. We used 6 mil plastic, but it didn't stay above freezing. I didn't lose any plants though, so that was good. I started another thread about using barrels of water for heating, but we decided not to put it up this year since we are moving, maybe as early as next Spring. I knew if I had put it back up, I'd just fill it with plants and seedlings, and I've already got more than I can handle to move.
Love the pictures Debra!
