Very clever, I've spent many a few minutes trying to see where the hook is. We've had to use command hooks all over this house as OH won't let me bang anything into the plaster, needless to say I had a clock (which I loved) fall off the wall and smash. Other things have managed to stay up though.
My friends, as I have discovered myself, there are no disasters, only opportunities. And, indeed, opportunities for fresh disasters.
