Hanging hammocks?

I've been thinking about how to do it but can't decide on what would be the best choice. I picked up some grommets and some rough fabric so I could either make holes with grommets or loops with fabric but i have no idea what kind of hangers to use or how to attach it to the cage and the hammock I would rather use a sort of chain then paper clips or safety pins because I don‘t want them to be right at the roof of the cage. what do you use to hang yours and how do you attach them?
