These panels can also be put together in a circular configuration to make a large bin for yard waste. Since I don't have time to cut everything up, and can just leave it to rot for a couple of years, having much larger bins is really handy for my 1-acre landscape. I grow squash on the mounds after moving the panels to a new spot, then spread the finished compost on my veggie beds, allow the weeds to sprout for a while, get rid of them, then plant. For a more visible spot in the front yard, I used a 3' x 15' piece of black lobster trap wire set up in a circle with the ends clipped together, which is even nicer and easier to move.
I've had a bunch of these for almost 20 years now; simple to use, they work great and pretty much last for ever.
It came bent, kind of bowed in the middle. I had to flatten the panels out and now they are kind of wavy. Fortunately, I was still able to put it together. I guess it will work and it is nice and inexpensive. But it's cheap because it's, well, cheap.
