I have just gotten a kitten and live in a cat containment area. My backyard is quite small so rather than building a cat enclosure I am thinking I will just put a net over the whole backyard. The two sides are so narrow, 900 to 1200 mm I am just going to attach the net to the fascia and to the fence. What is the best way to attach net to a colorbond fence? I need to do this as cost effectively as possible, and am very capable of doing the work myself. I was considering using some shade cloth for some of it to reduce heat and glare coming in to some areas of the house.
The largest span I have for the rest of the yard is 3m. It is my understanding that I will need to run some support wires to stop the net from sagging too much across this distance. How would I attach these to the fence?
