This tutorial site is in French, but pictures speak a thousand words... Wonderful work and you get to see how it was done, ideas, ideas, ideas!
I came up with this idea using small candle brass parts, buttons and beads. Glue them all together. Put a bit of sealant inside the bead to cover the hole. Give it a couple of turns with the spray paint and glue on a decorative label, either like a transfer decal or just printed on normal paper.
I KNEW those jean snaps were good for something!
