Use mirrored laser printouts or laser copies (no inkjet printouts). Coat the candle and the back of the image with a soft flat brush. Press the image against the candles evenly, using a squeegee or the like, and allow to dry for 24 hours.
After the drying time, soak the paper layer with a sponge and rub away the wet paper fibers.
Then apply candle transfer wax again to seal the motif.
