@LadyDennaRahl I don’t know much about smudging practices, can you use an abalone shell? I have seen those used when learning the differences between Native American smudging & our cleansing practices.
Before you go buying candles, please keep in mind that white candles can substitute for any color & you can use chime, birthday, tealight, pillar, votive, 1 or more wicks, jar candles (some can maybe double the intent if the color & smell correlate with what you are doing.
