Just hung a couple of pictures. It was a PITA, because they were a diptych, so they had to be at exactly the same height. Also, the grouping is centered on a fireplace, so the left-right spacing was critical, too. AND the length of the hanging wires differed between them, so the nails had to be at different heights for the pictures to be at the same height. I boofed it by 1/4", and had to rehang them. Looks good now, though.
