Here is our solution for hanging HolidayCoro's PixNode Flexible Net (https://www.holidaycoro.com/PixNode-Net-RGB-Pixel.../775.htm). This is currently designed to work with the 2" spacing net (and would probably work with the 3" spacing)

You screw the bracket to whatever you're mounting it to (in my case, a tree in my front yard), slip the net over the fingers, then you drop a 3" screw or bolt through the holes at the tip of the fingers, and that keeps the net from sliding off the fingers.
