Forgot an important detail. There was a kind of holder - scarf like - that was attached to the wall. So it was easy to hold them to the side when needed. At the end of the holder scarf there was the round brass object sewed on. ( central piece of the necklace) With the little snake hook (right in the picture) the holding scarf could be connected to the wall fixture.
oh yes - i've seen these before... the way to draw the curtains back... yep! i love those :)
