@raum I also have a few rolls of nanocord which is a small version of paracord. It is like a thick , strong thread.
I have black, white, camo, and orange and mostly use them to repair things or hold something together while epoxy sets up. I used a few short lengths of black to fix the bug zapper I have out by my pond. I hose it off into the pond every morning so my fish can have a good meal. All that water caused the supports that hold the grids in place to rust out and corrode rendering it useless. I tied the grids in place with nanocord and it works great. That thing will last forever now.
I used some long lengths of camo nanocord to dissuade a certain blue heron that visited my pond from enjoying some sushi. I made a few criss-crosses over the water and near the edge so his legs would get tangled. He did not come back and my fish are happy.
