In my hoop coop and hoop green house, I used roofing nails placed about every 12" along the bottom framing of the structure. I then used braided nylon twine (like mason's twine) to zig zag from first nail on E, over the top, to first nail on W, back over the top to second nail on E, over top to second nail on W... rinse and repeat all the way to the end. This gave a zig zag that held the tarp or plastic tight to the frame and prevented it from abrading against the frame when the wind buffeted the structure.
I will do the CP for trellising some tomatoes & beans this year. Already have tire/arch CP hoops partially set up for the 3 different Kiwi vines. Also plan on fencing around the coops, w/ HC on the lower portions, to allow to all chickens some "free range" w/o allowing any predators in. Thinking about using a CP arch/hoop in the front of our home, attached to the house and arched over the walk-way, w/ some type of vining plant that will block light & heat on our bedroom.
Our 3 hoop coops were originally made w/ chicken wire, but a move to new property proved we needed better predator protections. So HC was added to the bottom portion of the "walls" and as skirting around these CP/chicken wire structure.
A temporary shelter for pony feed & equipment when on leased property for 3 months between moving out of leased farm and closing on/moving into new property. Hay string was used to strap the pallets together, tie the two panels to each other and to attach the tarp.
When moved into the new place, did two "new" feed sheds to house feed & equipment at the two other paddocks for ponies... Fully meant to go back and turn the temp sheds into permanent w/ cinder block footers & screwed together, but 3 yrs later they still stand w/ hay string holding locking everything together.
Horse & pony hay feeders (doesn't work so well for big horses - they reach over the top of the feeder and bend it all up, LOL). Temporary & movable 16x16 "stall" for new baby & mum on grass (tied with hay string of course)...
In 1999, a 40' round pen for daughters (oldest, Skye, pictured) to learn to ride in and in 2017 a 60' round pen for granddaughters learning to ride (Skye's daughters) & large enough for training pairs of ponies to drive together or work a full size horse..
