I was pleased to find these candle carving instructions through One Stop Candle. Plenty of people have expressed an interest in learning but classes can be very expensive.
I imagine candle carving takes a lot of practice and I think it would be best to do one at time until you get it right. No harm in mashing a candle up and remelting it to try again either.
