Clay, molding materials?

[themenow.livejournal.com]

I found some really awesome lotus flower candle holders in the most recent catalog of At West End. The thing is...I'm pretty sure I can make this on my own, but I don't know what kind of clay or molding materials to use. If I use some homemade molding clay with flour, won't it dry out and crack? I don't have a kiln so obviously it won't be the exact same at the candle holders in the catalog.

What do you crafty grrls think? Any ideas?
