My friend Olivia and I were just discussing photo walls and feature walls, as she's just bought an apartment and has a blank canvas with which to work. I saw a great photo wall recently in a magazine where the frames were all white, small, decorative French Provincial style. It looked really gorgeous and was a nice point of difference to the usual black frames with cream or white mountboards like what I have - pictured. Then again, it does depend on what type of photos you're framing. Pretty white ones are great for family snaps, whereas the darker frames with mountboard give photos a kind of gallery look.
We were also discussing whether feature walls have had their day, and whether a wallpaper feature wall is better than a painted one. Open to discussion. Post your comments.
