In the beginning, they probably gave the monks plain candles, but over time, the more devout Buddhists would decorate the candle or carve it into intricate designs. We have now gone from normal candles to these 15 meter long floats that depict scenes from Hindu and Buddhist mythology. The normal Candle Processions still take place all over Thailand at this time, but the big floats first started to appear in Ubon Ratchathani about 34 years ago. Ubon is still the most famous though a few other cities now copy them.
