Hello ladies,,I dont make candles,,BUT I have done this with ready made ones,,and it really ISNT dangerous,,the way you do this is: you cut the design out of the one layer of the napkin,,and pin the napkin down on the candle and use a heat gun to saturate the napkin INTO the candle..this way it burns just like the candle,,I have done this LOTS and have burned them LOTS..and have one right now that I did for valentines burning right now, it burns all the way down,,
