20 paper double-sided adhesive dots, 2 cm in diameter and 1.5 mm thick, are a handy way to stick a candle wick to any surface, even an angled one. Simply peel one dot off the backing, place it where you want the candle to go, then press the candle onto it into an upright position so it burns properly. Double-sided adhesive dots are also useful in other areas of creative crafting.
