At the risk of inciting vicious sectarianism: what hardware do you use to hang larger thangka?

Tashi delek dharma friends! I’ve got a couple larger (20x30” image size) thangka that I have hanging on rather ugly finishing nails (in standard drywall). I went this route to make patching the holes easier but I’m pretty sure I’m not changing things around anytime soon and would like to replace the nails with something a bit nicer (and easier on the silk hanging string).

Obviously even at this size they’re still fairly lightweight so I’d like to stick with something effective but not unnecessarily cumbersome/invasive. Any advice is appreciated, thanks!
