Okay, just a little joke on Michelangelo's painting 'The Creation of Adam' in the Sistine Chapel. I was doing an Open House a few years ago and could not help but notice that the owner had hung the artwork too high. Now, admittedly Adam was a print taken from the original that is painted on the ceiling of the chapel BUT the owner's attempt to get this painting as close to the ceiling as possible was just a bit bizarre.
The recommended gap between the sofa and the art is 6 - 8 inches. The owners went a little too high. There is a plethora of information about hanging art here in AR and just generally on the internet. I use it, every stager uses it and now (when you see how ridiculous art hung too high appears) so can you.
(I took this photo with my blackberry and then used IPiccy to crop and frame the photo. I think it was Alan May who recommended IPiccy as a replacement for Picnik - sigh - and it is an excellent alternative to the software that is about to be removed from use.)
