SWMBO got a painted piece of slate with our last name, etc. that
measures about 12"x12" and has a leather picture-hanging cord. Need
to mount it outside on our stone facade next to the front door.
Problem is that it is very windy where we live, with gusts to 30mph+
very common. I need some way of securing it to the facade other than
just the leather strap hanging from a nail or it is going to rattle to
the point of driving us crazy. Any takers?

Hot melt glue. It's the next best thing to duct tape. Cheap, fast, easy,
can be used for a zillion things, and is removable without damage on
many surfaces.
