This is more for the chainmail side. I have seen people using a pole/stand system. Where they get a skinny rod and loop the rings around it. Then they put the rod on a stand, so they can easily work on it. Where do people get these stands/rods at? Or do they make them? I feel like this would be extremely for some situations.
