I have a large mirror in my bathroom,what can I use to frame it?

You could use molding, with wood medallions in the corners if you don't want to miter the molding. Here is a post that shows how to do both ways: http://www.momtastic.com/diy/128900-how-to-frame-a-bathroom-mirror/#/slide/1

My sister-in-law framed hers with a 3 inch wide layer of sand and then various shells glued into the sand. It looks wonderful.

maybe stickers with border design, or decorated Styrofoam 2x4s which you could either glue or double side tape it.

You can measure the mirror and go to any framing store and have the frame pieces cut for you. That way you can select whatever style you like.

Try and frame it with metal ribbon
