/cgl/ - Cosplay & EGL

What would be the best way to hang a really big charm in an ita bag? I'm making an ArS themed pouch for my art supplies but the charm I bought of them is huge. It came with a small chain but it always tilts to one side.

At the moment I use a thumbtack to keep it on a cork board, should I stick with something like that and attach an earring back to it?
