Hanging frames

I crossed an item of my list (woot) and hung these photos the other day.  I had started with pencil and level/ruler, measuring, calculating, erasing ... and that was taking too long. I then found this  diy paper template method for mounting photographs/pictures/frames ... SO.MUCH.EASIER. FASTER. Almost instant. And accurate enough for me!

BUT, I was not thinking far enough a head. This may not be such a good place for frames after all ... too much reflection.
