Candles can be easily decorated by the following method: The designs can be selected from paper prints which are tightly wrapped around the candle with the design in contact with the wax. Strike a match and play the flame over the back of the paper. Allow time enough for the melted wax to harden and then remove the paper. The print will be transferred to the wax.
Select designs that are not larger than the circumference of the candle. A good impression of ink on thin paper works best. - Contributed by J. J. Kolar, Maywood, III.
