I’ve been designing a gallery wall (pictures on the wall), so I thought this topic could be interesting for you too. There are several options, one of them is that you put the picture frames directly on the wall, the other option is to put the frames on a special shelves (e.g. IKEA Mosslanda), or this two can be combined together. Pictures can be photos, prints, posters, paintings, and the best is if you combine all sorts together. Be creative with the colors of the frames and the thickness of the frames . Here are some examples :-).
