Thoughts on making this permanent

A few months ago I decorated a hallway with crepe paper for a birthday party. Turned out I kinda loved it. I left it up, but obviously the crepe paper got weird with humidity and breezes coming through the hallway. I want to make it permanent, but I’m not sure how. Fabric is the obvious first thought…but if I hem it, I think it will stiffen it too much. But if I leave it unhemmed it will probably look too arts & craftsy over time. Im also not sure how I would affix it to the ceiling… Any suggestions? Maybe a certain type of fabric? Or a certain way of “loosely” hemming it? Idk….at this point I’m just making things up 🫣
