The trend of hanging empty frames as been around for several years now. I haven't latched onto it myself, but I can't say I oppose it. Antique frames in particular have remarkable craftmanship that is worthy of display in its own right. The trick is to do it in a fresh and innovative way. For instance here, I love how this oval shape frame was hung on a wire, and its gilding picks up some of the other hues in the room. Have you ever tried decorating with empty frames in your home?
