Let's banish bare walls. Because after seeing professional organizer Fay Wolf's Silver Lake apartment, there's no excuse for leaving a naked wall anywhere in your space. Instead, fill your big wall up with lots of little pieces that you love. You don't even need frames, just grab some binder clips and tape and let's go.
The expanse above the sofa is a tough place to fill for a lot of home decorators. You can absolutely splurge on a really big piece of art for the space, but if that doesn't fit into your plan (right now or, like, ever), try this idea out: Collect nine or 12 (or some other easily divisible amount) smaller pieces you like and lay them out in a grid above the couch.
They can be photos, prints, patterned paper, even magazine cut-outs–the only real requirement for making this look good is that they all be about the same size. The hang them up on the wall in a perfect grid with small nails, clipping up loose paper with tiny binder clips. The spacing is totally up to you, but you see how keeping a lot of negative space between the frames (like Faye did) really helps to fill the wall.
Symmetry and grids not your thing? You might be a creative type. In that case, you could use a really big inspiration board somewhere at home. Faye's corner office space is decorated with a collage of art, print-outs, and note pad doodles bleeding out across the wall. If I had to guess, it seems like the kind of thing that came together over time, so if you'd like to get started on your own free-form wall collage, start by taping to the wall a few things that inspire you. Let it grow as you find new muses, just make sure you keep a colorful roll of painter's tape or washi tape around.
