Hung Painted Frames

The picture frames I painted, finally got hung. Yay! Now they need to be filled. All but one.
We have this narrow bit of wall between the stairwell, and the archway to the living room, from the dining room. It is where the chimney is, so there's not much to do with it, but because of the architecture of the room, there's also not very many places to put things on the walls, so it's hard to decorate the dining room.
