I sometimes will mount a work (photo or painting) in a temporary frame and hang it over the toilet. I figure I will then encounter it casually a number of times each day, without consciously setting about to evaluate it. It always "just happens to be there." After a few days, I've formed an opinion about it's state of finish that is much more grounded and less the result of a forced critique. It also brings the whole nobility of fine art thing down to reality -- the picture is hanging in a bathroom!

Funny, but my wife complains when I do this that she never sees the work...
