Ombre Votive Candles: Margarita Lime

I recently purchased a votive candle from East West Books in Mountain View that has the look of Ombre.  I was wondering how it was done. In my search I found this Margarita Lime Ombre Votive Candle recipe from Wholesale Supplies Plus.  It is an advanced projet that should take an hour to make and yields 16 votives (8 clamshells).  According to Wholesale Supplies Plus, Ombre is a huge trend for Spring '12. The term Ombre refers to a graduation of color (fading from dark to light). These candles show off a new technique to mimic this current trend, and they smell as pretty as they look!
