Can you hang a painting from two pegs, so that if you remove EITHER of the pegs, the painting will fall down?
ok simple to do hard to explain...
two nails inline vertically. Make a loop with the wire and place it over the top nail and loop it onder the bottom nail. ensure the wires originating at the painting are both outside the bottom nail or it will snag. Voila. Try it for yourself.. a picture would be easier but i hope you get it.....
