Thanks! Well...this one has already broken once fairly easily, so I wouldn't trust it to actually be worn. I'm just gonna hang it up somewhere to look pretty. I am accepting commissions right now... I could probably do a little better, considering this one was my first try. But I couldn't make any promises about how long another would last as an actual necklace/pendant.
If the clay's too brittle, you could maybe make a mold from this one and make another out of a sturdier material... Maybe one that could withstand being drilled through for a little jewelry ring at the top for the cord to pass through?
