I love your ideas to change the tile and add more trim to the mantel, which I would love to do in the future. For now I was really just wanting a quick fix! I would love to get a whole new mantel someday but I really gotta pace myself. : )
I decided to paint the mantel and leave the screen alone for now. It is the quick fix I was dreaming it would be, so bright and cheery!
(I chose to paint the mantel instead of doing the laundry while the babies were sleeping... I know I am so bad but this is so much prettier!)
