Technique for temporary mounting of 10 mirrors

I had this set of mirrors I wanted to hang in my hallway. But I needed a way to hang them temporarily to test configuration and placement.

Each mirror hangs by 3 vertical pieces of white artists tape. Each strip is several inches long to have plenty of length to stick to the wall given the weight of the mirror. The strips are reinforced on each mirror with a horizontal piece.

Over the course of two days I could move each mirror around easily without worrying they’d fall down. Once I settled on a configuration I used a special museum putty to secure the mirrors in their final position.
