We would strongly recommend that all externally positioned plaques are positioned vertically via the wire hanger. External products should ideally be placed away from the elements in winter (November - February) perhaps placed in a shed or outhouse to avoid the worst of the elements. Should this not be possible moving to a sheltered spot would be recommended. Please place products on the floor carefully as edges could chip or break if mishandled. Some of the heavier Ornaments may need 2 people to carefully lower to the ground especially if that is a hard paved surface.
