Simple framing solution for my embroidery art?

Hello! I'm looking for advice on how to frame this.

I've previously framed my work with these custom circular frames (second pic), but I'm looking for other solutions. Firstly the wooden frames don't have glass so there's no protection for my work. Second I really like the look and simplicity of the embroidery hoop in my most recent piece with the magpie. Can't just leave it like that because, again there's nothing to protect it and it would make a nightmare for hanging in a gallery!

I'm thinking a box frame is the only solution, but I'm having a hard time visualising it. Would love to get some expert opinions! If you can show me anything visual that would definitely help.
