People ask me me help them hang art all the time. When I look at the piece and the space, I normally just know what to do. It's instinct.
However, when people ask me how to hang art, I don't have anything cohesive to tell them.......until now. Home Design Find has the most wonderful how-to article on hanging art.
For example, it says to "Keep your art centered at eye level".
I'm not just going to copy and paste the article, so I strongly encourage you to go to their site and read it.
