I've just priced up what it would cost to make.
For 10 meters of waxed leather cord is £1.50 and you can pick from lots of colours, I've found some silver hoops and a rectangular shape for £3.50 and £2.50, then whatever charms you want on it.
So not quite £80
I've just been sent a catalogue from a jewellery supplier I use.
Its PJ Beads if you want to look at their online shop.
