Peacock Diamond Clock

So I stepped up my game for the diamond painting and decided to do a clock.  Believe it or not I really do love how it came out.  I’m just now stuck with on how to mount this so it’s behind glass to stay clean and yet at the same time have enough room to put the clock in so that the hands move freely along with access to the back to change the battery if needed.  I may have to enlist the help of my hubby for that part.
