candle magic is the easiest magic around, getting more complecated as you go on. take a candle with the colour associated with your problem, charge the candle, then light it. watch it burn out visualizing your problem being fixed.
there, a basic candle spell. as you go on you can carve things into the candle like symbols and names, anoint it with oils to increase the power, say a chant, burn paper with a wish upon it, add multiple candles, repeat for weeks on end, it goes on and on with the possibilities, but that's the most basic. the hardest part of any spell is charging/visualizing your desired outcome.
