I made an earring holder using a picture frame, but it wouldn't stand up easily on my dresser. So, I made a completely freestanding earring holder out of an old box, some newspaper clippings, and cross-stich mesh. I added a few studs to decorate.
Here's the front:http://www.chicpolitique.com/images/craftster/holder_front.jpg
From the side, you can see the shape of it:http://www.chicpolitique.com/images/craftster/holder_side.jpg
And the back:http://www.chicpolitique.com/images/craftster/holder_back.jpg
The key is the slanty shape, because it gives extra weight on the bottom to prevent the holder from tipping over. It also makes it easier to see the earrings.
This is the way you need to cut your box:http://www.chicpolitique.com/images/craftster/holder_diagram.jpg
You get two holders from one box!
After I had the basic shape, I decoupaged on some newspaper clippings, and hot-glued on a rectangle of cross-stitch mesh.
The holder is quite portable and ever-so useful.
