Part of one of my first jobs was using the hook and double loop
tie wires to tie up 50 lbs. bags of coal. That was many decades ago.
This is the wire I have using to hang parts for painting. I didn’t
know it was iron. Searching iron wire found its also available in
smaller diameters which may be more suitable for what you
have planed if you can find it where your at.
