We'd just gotten our superb new photos back from Fracture, frameless, printed on glass, but were having a heck of a time getting them hung just right.  The real problem was lack of minute adjustment: left-right, up-down.  Spacing and alignment are critical in hanging a triptych.  After a frustrating week of drilling and filling and fidgeting--getting almost right but not quite right--I hit on "a" solution.  Let me know what you think of my idea.
