I use 2 inch bird netting from Amazon for the top, I use the yellow poly-wire around the edges on mine with those insulators Howard showed. I have about 4 strands of wire around the fencing as I have really smart persistent predators here. https://www.amazon.com/Netting-Bird...=1522848729&sr=8-6&keywords=game+bird+netting I have had some up 5 years and the snow has not taken it down yet. I have one I have to drop this year and remove the branches from it and hang it back up. Works great..
