1- Hanging Art the Wrong Way.
Art hung the wrong way on a wall is like a character in a movie wearing a really bad costume. It doesn’t ruin your experience, but it’s just terribly distracting.
Whilst most generally agree that art should be hung at eye-level, our designers stress that this doesn’t apply in every case. “Yes, the art should be at eye level, but not if your ceilings are unusually low or high.” explains Zylus designer Gale. “If the wall were cut up vertically into four sections, think of the art being in the third quadrant if the ceiling is 8-10ft. high. For exceedingly high ceiling a vertical work is a perfect complement to tall walls.”
If it’s a collection of art then you need to treat the whole collection as one piece.
