Working on my eclectic little gallery wall, I think it might be nice to have a silhouette. They are so classic, and no longer apply to only your children. This gallery wall is all silhouettes, but they're all so different which gives it great dynamic.
Other than a classic silhouette on your wall, these other ways to add a classic touch to your life are so sweet, and will definitely catch the eye (and envy) of all your friends.
