Not really a question, I just recall it having various methods people have done with a couple handslap on the forehead methods that I don't recall.
My wife recently had two 24x36 posters framed in big freakin heavy nice frames that I have to hang. Goal is to have them not fall down, not look loke a moron hung them, and not be extremely difficult. Bonus if I can later move the picture and be able to touch up where it was at (not that a woman would ever change her mind on where a picture should go).
Family Handyman had an article on it a couple months back (website search ends with 2005) so I need to flip through that as well.
As usual, I'll spend 5x the time researching something that it will take me to do it.
