How to decorate a 5 by3 wall mirror what can you put on it?

Is it framed? If not, i would add a decorative moulding around it. Here on Hometalk many people have done mirror projects. Type in "mirror" in the search box - you will have many examples - choose something that makes you happy and blends with existing decor.

That all depends on your decorating style ,no one elses

If you go on you tube n type in "how to decorate a mirror frame" they have alot of good ideas. Or Pat Catans or Michaels, n type in the same thing, they also have great ideas! I hope I helped you in some way.

I've recently seen products to update mirrored closet doors and they were amazing...I'm not a fan of those closet doors at all and I loved the transformation. You could fram the mirror or add more items for a gallery wall. There is also a method to age the silvering.

paint a picture on the mirror used decals or tatuage hope this helps
