Seven knob candles (also known as wishing candles) can be thought of as analogues to knot magick – either building or releasing energy or the intent of the spell or ritual as each knob is burned through. An entire candle can be used for one wish, burning one knob each day for seven consecutive days. The wish should be written on white unlined paper or parchment paper and placed beneath the candle and burned in the candle flame before the candle is finished burning. Or, the candle can be used for seven different wished. Write each wish on a separate paper, burn in the flame of the candle. Always SNUFF OUT a candle – do not blow it out!
