What am I going to put in it? Maybe you've asked this question or thought about it a few times.
The wall of the sofa can be very useful, to propose a more cozy atmosphere in the decoration of the house
Pictures - Making a composition with pictures is practical and more usual.
Gutter shelf - For those who can't drill the wall, here's the solution, for pictures.
Furniture - Bookcase, a sideboard, buffet, if there is space and it doesn't disturb the creculation, a good option.
Mirror - can be the highlight of that wall, and if the reflection is visually pleasing, even better.
Creative Crafts - A handmade art, a macramé panel, a cloth, are always good options.
