Well, let’s face it. You can make anything with 550 cord. I’m currently macrame-ing an evil TUAKmobile with JATO bottles, ejection capsule and quad 20mm autocannon. It’s not going well: Do you know how much Arrest-me Red 550 cord costs? Weaving it in sufficient density to ward off 30-cal rifle ammo has been a challenge, financially if not technically.
But in the meantime I repurposed a disused interior clothesline into curtain holdbacks.
This cord holding up the chickens’ top cover has been under substantial tension for several years with no sign of deterioration. With a snow load that thing gets heavy.
