Greek key adds such a sophisticated, elegant, and graphic quality to any room that it requires a place in my Chinoiserie top ten. Check out my April Houzz Ideabook (link in my sidebar) for over 50 of my favorite Greek key ideas. I am so inspired by the O'verlays Greek key transformations that I have included a gallery below the vignettes by Joe Nye and Ruthie Sommers. These O'verlays have taken the DIY world by storm. They are a fabulous and budget friendly way to dress up a vintage or Ikea piece or even your walls or woodwork.
