Please do not accuse me of being a loose man, I know how to suddenly turn purist if needed. Here the proof to redime myself:
In the first one (Indian openwork with Venetian arabesque beads) you could believe it is an antique traditional Indian adjustable string. I went as far as rubbing the cords with oily hands (mustard cooking oil, then with some sandal oil to finish).
The second example is a Sind wedding necklace of which only the loose beads came to me. The beads are of course antique, but at the back, salvaged old Indian threads were used. And it smells ethnically, too!
Labor costly.
