I am very happy with my concrete reinforcing wire. One layer of that, add one layer or chicken wire or whatever you have on hand, and you have reached perfection.
The thick wire of the concrete wire supports itself well. So, it needs little in the way of supports, really just on the edges. Also, that strength means it does NOT bend or break under a snow load!add a layer of thin wimpy wire to keep out small critters, and there you have, perfection!![]()

Perfection!

It would look cool on Google street view too!
That's what's important to me!!!
