You weren't using one of those "special" glass ornaments that are bought separately (not in a box of 12, etc.) and come in shapes like ovals and hearts, etc., were you?
No, they were definitely the thicker round glass ones. Like I said, shirtless Hugh Jackman was more of a factor in that particular accident.
(Oh, you can Netflix the Hugh Jackman "Oklahoma!" DVD, I highly recommend it!)
What I did was do an initial covering with a thin (4 or 5 on the pasta machine) layer of *extremely* well conditioned red, purple or green Sculpey III. Sculpey III is the softest of the polymers, so there is less chance of breakage when putting on the first layer.
After baking, I did a bit of sanding to smooth it out and covered the ornament with mokume gane, chrysanthemum canes or whatever struck my fancy. This second, decorative layer was made with either Fimo or Premo which are stronger.
