Scrap Wood

I had some scrap wood leftover from the "tool tote" project below.  I hate to just throw out a nice chunk of walnut wood, so I thought up this little accessory.

My better half is always placing her earrings and jewels on the little half-wall of the bathroom.  I fear one of the kids will yank her jewels over the edge and lose them forever.  This is the problem:

And this is my solution (at least I hope it solves the problem):

My walnut wood scrap turned into a little organizing dish.  

Notice the little edges that fit nicely over the edges of the half wall.
