All I did was order a personalized monogram off of etsy by searching for "vinyl monograms". There are TONS to choose from. I have a friend that makes these also here. These are ones you could put on a wall but I LOVED the idea of putting it on a mirror. I wanted a chunky gold mirror and couldn't find exactly what I wanted so I ended up going to a custom glass place here in town and having them cut me a mirror to fit a frame from hobby lobby. And then I had Hobby Lobby put it together for me. The vinyl was hard to get on. There are air bubbles and it doesn't look perfect but I think it will look good on the wall anyway.
And the ideas are ENDLESS.
