EVER WONDERED WHAT it takes to hang hundreds of paintings perfectly? Apparently up to six people and mad math skills. That’s what Frye Museum exhibition designer Shane Montgomery claims. But he also claims you could get by with just the basics—and a good eye for symmetry.

1. Determine a viewing height and have a friend hold the picture while you mark the bottom of the frame’s position on the wall with masking tape.
2. Measure the distance from the bottom of the frame to the hanging hardware on the back of the frame, and make two corresponding marks on the wall.
3. Take a floreat picture hanger and attach it to the wall with a hammer (use two floreats for maximum stability). Place the picture carefully onto the floreats, taking care not to scratch the wall paint.
