Ok so this isn't exactly pretty. But it's fast and easy and cheap to make. I went to Jo Ann Fabrics for this one. Get the plastic grid that is used for needle point and cross stitch. (It costs less than $.50) Then you can grab a ribbon. (I purchased a bag of scraps for about $1.00)

Cut the grid in half to be more manageable. Then take the piece of ribbon and tie it to the top of the grid in a little loop.

Then you can thread the earrings through the little holes in the grid. Hoops fit easily on the bottom. I only put my dangly big earrings on this one, and put the studs in a box, but the organizer can hold many studs too.

I have seen some that have little frames round the edge and other embellishments, but here's the quick and easy version.
