HELP! My fireplace needs desperate love.

By fireplace, I mean the "fake" fireplace opening created by new mantle.

After hosting my last Christmas party of the holiday season yesterday, it is time to take down the Christmas decorations.  This left me with the feeling that now is the time to tackle the opening of my "fake" fireplace. I have always longed for a mantle to decorate.  This fall, my friend, an architect who was remolding an historical home, called me and asked if I would like a mantle. Well absolutely!

Here is what I have... The mantle and "fake" fireplace. 

I would like a creative, unexpected way to fill the opening that creates some type of illusion.  That is where Pinterest comes in. Of course, Pinterest saves the day. I have collected several concepts and am now evaluating the alternatives. This is where I need your help.  Which do you like best?

I initially thought I would paint the opening black or drop black printed fabric down.  Instead, I am considering putting a large chalkboard inside such as this...

After filling the space with a giant chalkboard, I considered painting the black fireplace screen that my mom Santa brought me to a bold color like shown in the "screen solution" photo above.


That is far as I am in the thought process. Any suggestions?  I know much help is needed!
