I thought I would post a few photos of a painting installation mock-up our Installer/Designer came up with. Apparently he will only have a day or so to hang an entire show, so he decided to mock-up the walls like you see below:

He cut butcher paper the exact size of the paintings, hung a string for our hanging height and then simply folded the paper in half to get the painting center line.

It should be short work on hanging day for one person to measure for the hangers right on the paper, hammer them in (or perhaps mark them through the paper) and pull the paper off.
It also helped the vinyl lettering guy install text on the walls.
So, if you find yourself with time on your hands a few days before a super short time-frame install, try this out.
