A. Invest in brick clips. These snap-on metal devices with integral picture hangers are easily clipped to the face of a standard brick, as long as the mortar joints are not too prominent. The toothlike top edge grips the top of the brick while the U-shaped spring at the bottom of the device holds it steady along the brick’s lower edge. Use two per picture to ensure a sturdy and level display.

Brick clips cost $2.95 each at Picture Hang Solutions in Hillsborough, N.C.; discounts are available if you buy in bulk. (For information: 919-732-8364 or govart.com.)
