@jennifer1983 you have gotten a lot of great advice and I really have much more to add! Lol.
There are absolutely no stupid questions. Except the ones you don’t ask.
I like many others have stated use chime candles and tea light candles. If I use a bigger candle, like many others I will reuse it for a different spell. If I do reuse it, I be sure to use it with a spell of similar intent. For example, if I use a candle in a certain voodoo spell I have a certain place I put just voodoo reuse candles. No have a special place for love spell candles, a place for abundance candles, etc. when starting a new spell I always check the used candle spot before lighting a new one.
