I made a finished piece with one of my resin pendants from a few weeks ago. I had a large-ish wooden bezel, put in some pretty floral background paper, sealed it a million times and poured a clear coating of resin.
I used a glue on vintage brass bail, added some wood, stone and a couple of special carved beads. I wanted it to be long enough to go over my head, like I do everything these days, so I added some gorgeous vintage brass chain at the back. I love the rustic, muted tones. It looks like a hefty piece, but because of the wood, it is not an especially heavy necklace.
