The whole empty frames thing has been much derided as lazy or ghetto or less-than-creative, but I still like it and think it can be a whole lot of fun if hung in something other than a grid. The look works especially well if you have some nice frames that will stand out on their on. Conversely, you can play around with frame orientation until you find art that you like that also fits into your budget.
Sometimes you can have too much of a good thing, but I think that in this case more is more. The empty frames being so colorful doesn’t hurt one bit. (via)
You don’t need to go crazy, especially if your empty frames are larger and particularly striking, like these.
Of course, it’s not like you have to commit to keeping all your frames empty forever. Mixing empty frames and frames containing some kind of image is the moderate (and now quite popular) way to incorporate empty frames into decor. (via)
