The candles are very easy to make. All you need is decorative tissue paper, wax paper and a heat gun. I cut a sheet of paper about 6 inches longer than the circumference of the candle (how round the candle is). Placing the candle on the paper, I hold the ends so the paper is tight against the candle and apply the heat gun. The wax from the wax paper melts onto the tissue paper.
Moving the heat gun smoothly along the candle insures few chances of creases and seals the paper as if the candle was manufactured with it. There are lots of YouTube videos on how to decorate candles this way. Here's one of them: https://www.youtube.com/watch?v=t-R_MBFO_CU
