The big zip ties I am talking about are BIG zip ties. They might be more than you are looking for to zip up the fencing. I was thinking more of using them for tying bigger stuff like the pillow itself to an existing underwater structure. We use them around the farm to tie up hydraulic hoses on farm equipment. They are probably a quarter inch wide and 3 feet long. Not where I can look at one right now, but they definitely will hold a lot of strain. They would work great for like tying a Christmas tree to a concrete block or something like that.
Bought in bags of 100, they are pretty reasonably priced.
