My pens are quite large. I had to put up some of the netting up in sections and fasten the sections together. Originally I used cable ties but they eventually deteriorated so then I used hog rings. I made some wood T-posts to hold the netting up. This is an older picture but in the middle you can see a T-post. Good luck...
I bought this netting from Pinnon Hatch Farms for redtail defense but I am still trying to get it put up right. Right now I have it braced up with scew in hooks under the barn eaves and 8' 3/4" PVC with T's on top but it's not working. It's covering the run and saving the chickens but it's rapidly sagging under leaves and debris. I can offer 2 tips: 1) Get tall help and 2) Find the corners first.
Be careful and patient, this stuff catches on everything you try to drag it over.
If I ever do this again, I will start with a totally flat & empty field under neath because setting this over my coop & fencing has been the most aggravating thing I have ever done.
