Will you share your ideas for decorating an empty wall?

I have an empty wall in my master bedroom and I don’t know what to do with it. There really isn’t any room to put furniture against it. It is on the south side of the house w/ a small window. It’s a LOOOOONG wall too… The bed is close-by and there is enough space to walk back and forth to the bathroom. My walls are a buttery yellow and the theme of our room is shabby chic/cottage style….If you have any ideas or suggestions, please share them w/ me…it is driving me craaaaaazy….!!! ) Thanks!!!
