Art works come pretty low down on the fitting-in priority list when it comes to furnishing a small space. With the little wall space that you have, when it comes to choosing between a painting, a shelf, a cabinet or coat hooks, the painting is going to lose out every time. So, these shelving frames are cool, they can be made to look like 3D works of art and they can hold stuff on top of the shelf and suspended from the hooks below.
This shelf from the French website tikamoon, is really cute, but you will need to take time arranging your bits and pieces on it so that it all looks as pretty as a picture.
